Key Topics Covered in NCERT Solutions Class 12 Chemistry Chapter 11
Topics covered in the Chapter 11 Chemistry Class 12 NCERT Solutions are
- IUPAC names
- Classifications of
- Mono, di, tri, polyhydric alcohol
- Mono, di, tri, trihybrid phenol
The reaction of benzene sulphonic acid with aqueous sodium hydroxide is used in this approach. The salt is then combined with solid sodium hydroxide and heated to a high temperature to react. This process produces sodium phenoxide, which is then acidified with aqueous acid to produce phenol.
There are many methods of preparation of alcohols:
- Hydrolysis of Halides
- Hydration of Alkenes
- Hydroformylation of Alkenes
- Hydroboration of Alkenes
- Grignard Synthesis
- Nomenclature
- Physical properties
- Chemical reactions
- Structures of functional groups.
The NCERT Solutions Class 12 Chemistry Chapter 11: Alcohols, Phenols, and Ethers, contain step-by-step answers to all questions. Thanks to diagrams and examples of reactions, students can easily understand the creation of alcohols, phenols, and ethers. Students will also receive a review of Chapters relevant to hydrocarbons to fully comprehend the design of others.
The sub topics covered are
- Classification
- Nomenclature
- Structures of Functional Groups
- Alcohols and Phenols
- Some Commercially Important Alcohols
