Introduction to Carbon Compounds

Carbon is the core of all living organisms. In fact, it is the 17th most abundant element on planet earth. And Chapter 4 Class 10 Science highlights major carbon compounds and their properties in an elaborate manner. 

Carbon is a tetravalent element i.e., it has a valency of 4. In simple words, it has 4 electrons in its outer shell. Additionally, it has the property of catenation i.e. the atoms of Carbon can chemically bond within themselves into a chain-like series. How? Carbon can share electrons between two atoms to completely fill the outermost shell and then form covalent bonds with other elements like Oxygen, Hydrogen, Nitrogen, Sulphur, or as stated formerly, with itself. Moreover, carbon can form double and triple-bond compounds as well. All carbon chains can be further classified into 3 types – branched, ring, and straight chain.

Carbon’s atomic mass is 12.01 g mol-1, its atomic number is six, and is a part of the 14th group. Because of its versatility and ability to form bonds with every element, carbon is found in almost anything and everything. From its elemental state in coal to carbon dioxide in the air we exhale and as ethanoic acid & ethanol in detergent & soaps, carbon is a part of our everyday life. Did you know that carbon is a major source of fuel?

Physical Properties of Carbon Compounds

The two purest forms of carbon are coal and soot. They are soft, dull, and black-grey in color. Though there are lots of other carbon forms as discussed above, none of them is as pure as coal. Another important carbon compound is charcoal. The end result of heating carbon in the absence of air is charcoal. The density of every carbon compound is different and mostly dependent on the origin of the component.

Solved Examples

  1. How would you distinguish experimentally between an alcohol and a carboxylic acid?

Answer: Carboxylic acid reacts with Sodium Carbonate, produces Carbon dioxide gas, and turns lime water milky. On the other hand, alcohol gives no such reaction. By conducting this experiment, alcohol and carboxylic acid can be distinguished.

The reaction of Carboxylic acid with sodium carbonate:

2CH3COOH + Na2CO3 → 2CH3COONa + H2O + CO2

Q.1 Carbon is the sixth most abundant element in the universe. It has four electrons in its valence shell and forms covalent bonds. Due to its unique ability to form bonds with the other atoms of carbon it gives rise to large molecules that are exceptionally stable.
(i) Which property of carbon enables it to form a large number of compounds?
(ii) What is the valency of carbon?
(iii) What are saturated and unsaturated hydrocarbons? Explain with example.
(iv) What learnings for life can be associated with this property (ability to form bonds with other atoms) of carbon?

Ans- (i) Catenation enables carbon to form a large number of compounds.
(ii) The valency of carbon is 4.
(iii) The hydrocarbons in which the carbon atoms are linked by only single bonds are called saturated hydrocarbons, for example ethane.
The hydrocarbon in which two carbon atoms are linked by a ‘double bond’ or a ’triple bond’ is called is called an unsaturated hydrocarbon, for example ethene.
(iv) The learnings for life that can be associated with this property (ability to form bonds with other atoms) of carbon are as follows:
• In union, there is strength.
• Even weak can become strong when they are united.

Q.2 Water freezes at 0 ºC and is used in automobiles to keep the engine cool. However, when the temperature falls much below 0 ºC water cannot be used as it freezes and forms ice. Under these conditions, a mixture of water and alcohol is used in radiators to keep the engine cool.
After reading the above passage, answer the following questions:
(i) Give two reasons for the use of the mixture of water and alcohol in car radiators in sub-zero conditions.
(ii) The alcohol-water mixture on fractional distillation gives an azeotropic mixture containing 95% alcohol and 5% water by mass. What is this mixture commonly called?
(iii) Name the liver disease caused by the excessive alcohol consumption.
(iv) Which value of alcohol is reflected in using it as antifreeze in radiators of vehicles in sub-zero conditions?

Ans- (i) The mixture of water and alcohol is used in car radiators in sub-zero conditions because of the following:
· They form a homogeneous mixture, i.e., they are completely miscible in all proportions.
· The mixture has much lower freezing point than water, therefore it does not freeze under low temperature conditions.
(ii) This mixture is commonly called rectified spirit.
(iii) The liver disease that is caused by the excessive alcohol consumption is liver cirrhosis.
(iv) We may not be able to complete a task or achieve a goal independently but together we can.

Q.3 In December 2011, at least 150 people died after consuming toxic alcohol in West Bengal. The residents of twelve villages in the South 24 Parganas district fell ill after drinking the alcohol. Many more people were being treated in the hospital, with fear of the death toll rising. Several died at home; fearing police would take action against them.
Toxic alcohol deaths are a regular occurrence in India.
After reading the above passage, answer the following questions:
(i) As a science student, explain the major reason behind such tragedies.
(ii) Do you think we can use alcohol as an additive in gasoline in India?
(iii) Suggest two activities to prevent such type of tragedies in future.

Ans- (i) The main component of drinking alcohol is ethanol. It tends to slow down the metabolic processes and depresses the central nervous system. Hence, the individual may feel relaxed after the consumption of ethanol. To prevent the misuse of the ethanol that is produced for the industrial or medicinal purposes, it is made unfit for drinking by adding poisonous substances like methanol to it. This is called denatured alcohol. Methanol is a poisonous alcohol which causes permanent blindness and death.

(ii)Yes, we can use alcohol as an additive in gasoline in India. The gasoline need of our country is mainly met by importing it. The import of gasoline increases our fiscal deficit. To meet the energy requirements and to reduce the oil pool deficit of our country one should support the use of ethanol as an additive in gasoline. However, it must be regulated by the Government.

(iii)We can prevent such tragedies in future by:
· Spreading awareness by organising campaigns and debates
· Making warning labels
· Using mass media

Q.4 In our country, river Ganga is worshipped as a goddess and is considered the holiest of all the rivers. Unfortunately, today it finds its name in the list of the five most polluted rivers of the world. The project manager of the Ganga Pollution Control Unit at Haridwar found that one of the major reasons for this was the continuous use of soaps and detergents in an indefinite proportion for bathing and washing purposes.
I believe, since Ganga is the life-line of crores of people, so it is our social responsibility to make it pollution free.
(i) What is soap? Give an example.
(ii) Government of India has introduced several plans to save Ganga from pollution. Will you support the government’s plans or consider it a violation of the human rights?
(iii) Which values are promoted by keeping Ganga fresh and clean?
(iv) Suggest two activities that can help you promote these values.

Ans- (i) Soap is the sodium or potassium salt of a long chain fatty acid, which has cleansing properties in water. For example, sodium stearate.
(ii) I will support the government’s plans to save Ganga from pollution as it is for the benefit of all.
(iii) If we keep Ganga fresh and clean, we promote the following values:
• Concern for environmental protection
• Reducing water pollution
(iv) Some of the activities that can help us promote the above mentioned values are as follows:
• Public education through programs including: Plays, Concerts, Painting competitions, Conventions
• Mobilising, involving and working with local government to clean Ganga

Q.5 On the occasion of Diwali, Rahul’s mother wanted to clean their house. She asked Rahul to buy a bottle of bleach from the market for all the household cleaning. However, Rahul bought a bottle of vinegar instead of bleach as his father suffered from severe asthma and his mother had pneumonia last year due to which she had trouble breathing.
