Alcohols are an important topic in the chemistry syllabus for JEE Main and Advanced. Here’s a crash course on alcohols that will help you prepare for the exams.
- Definition: Alcohols are organic compounds that contain the hydroxyl (-OH) functional group attached to a carbon atom.
- Nomenclature: Alcohols are named by replacing the -e ending of the parent alkane with -ol. For example, ethane becomes ethanol.
- Physical Properties: Alcohols have higher boiling points compared to alkanes of similar molecular weight due to the presence of intermolecular hydrogen bonding between -OH groups.
- Preparation of Alcohols: a. From Alkenes: Alkenes can be hydrated with dilute sulfuric acid to give alcohols. b. From Aldehydes/Ketones: Aldehydes and ketones can be reduced with reducing agents like NaBH4 or LiAlH4 to give primary and secondary alcohols, respectively. c. From Carboxylic Acids: Carboxylic acids can be reduced with LiAlH4 to give primary alcohols.
- Reactions of Alcohols: a. Dehydration: Alcohols can be dehydrated with strong acids to give alkenes. b. Oxidation: Primary alcohols can be oxidized with oxidizing agents like potassium dichromate (K2Cr2O7) to give aldehydes and carboxylic acids, whereas secondary alcohols are oxidized to ketones. c. Esterification: Alcohols react with carboxylic acids to form esters in the presence of a catalyst like concentrated sulfuric acid. d. Lucas Test: Lucas test is used to differentiate between primary, secondary, and tertiary alcohols based on their reactivity towards hydrochloric acid in the presence of zinc chloride.
- Uses: Alcohols are used as solvents, disinfectants, and as raw materials for the production of various organic compounds.
Make sure to practice problems related to alcohols and understand the concepts thoroughly to score well in JEE Main and Advanced.

Nomenclature of JEE (Main+Advance) e-Crash Course Alcohols
The nomenclature of alcohols is an important topic in the JEE (Main+Advanced) e-Crash Course on alcohols. It involves the systematic naming of alcohols using the IUPAC (International Union of Pure and Applied Chemistry) rules.
The IUPAC rules for naming alcohols are as follows:
- The longest chain of carbon atoms containing the hydroxyl (-OH) group is selected as the parent chain. The chain is numbered from the end nearest to the hydroxyl group, and the carbon atom of the hydroxyl group is assigned the number 1.
- The suffix “-ol” is added to the root name of the alkane that corresponds to the parent chain. For example, if the parent chain is a six-carbon chain, the root name would be “hexane,” and the suffix “-ol” would be added to get “hexanol.”
- If there are more than one hydroxyl group in the molecule, the prefixes “di,” “tri,” etc. are used to indicate the number of hydroxyl groups. For example, if there are two hydroxyl groups, the compound would be named as “diol.”
- If there are any substituents attached to the parent chain, their names and positions are indicated using the usual IUPAC rules. For example, if there is a methyl group attached to the second carbon atom of a six-carbon chain containing a hydroxyl group, the compound would be named as “2-methylhexanol.”
It is important to master the nomenclature rules for alcohols as they form the basis for understanding the properties and reactions of alcohols.
