Topics and Sub-topics

Chapter 11 Grade 12 Chemistry Alcohols, phenols and ethers are an important topic because they are widely used in organic chemistry. They have always been part of some natural component and understanding their nature and function is essential to understanding chemistry as it is and also being prepared to learn more complex subjects at different levels. higher class. 

Vidyakul NCERT notes provides answers to each question in the text.  Students can tackle the questions by unit or by topic and continue to study them to perfection. The topics and subtopics included in Alcohol, Phenol and Ete Chapter 11 of NCERT Grade 12 Chemistry are as follows.

Alcohols and Phenols

Alcohols can be prepared by the process of hydration of alkenes or from carbonyl compounds.

  • Hydration of alkenes – When preparing in this method it is either in the presence of an acid or by a hydroboration-oxidation reaction.

  • Carbonyl compounds – When preparing in this method it is carried out by catalytic reduction as well as the action of Grignard reagents.

Few Important Questions

  • What are the uses of alcohols?

1. Alcoholic Drinks/drugs2. Industrial methylated spirits.3. Use of ethanol as a fuel. 4. Ethanol as a solvent. 5. Methanol as a fuel.

  • What are the properties of Haloalkanes?
