JEE (Main+Advance) Intermediate Course Alcohols

Alcohols are a class of organic compounds that contain a hydroxyl (-OH) functional group attached to a carbon atom. In the JEE (Main+Advance) intermediate course, you will learn about the different types of alcohols, their physical and chemical properties, and their reactions.

1. Classification of Alcohols Alcohols can be classified into three types based on the number of alkyl groups attached to the carbon atom bearing the -OH group. Primary alcohols: Alcohols in which the -OH group is attached to a primary carbon atom (i.e., a carbon atom bonded to only one other carbon atom). Secondary alcohols: Alcohols in which the -OH group is attached to a secondary carbon atom (i.e., a carbon atom bonded to two other carbon atoms). Tertiary alcohols: Alcohols in which the -OH group is attached to a tertiary carbon atom (i.e., a carbon atom bonded to three other carbon atoms).
2. Physical Properties of Alcohols Alcohols have higher boiling points than alkanes and alkyl halides of similar molecular weight due to the presence of the polar -OH group. The polarity of the -OH group also makes alcohols soluble in water.
3. Chemical Properties of Alcohols Alcohols undergo various chemical reactions, including oxidation, dehydration, and substitution.

Oxidation: Primary alcohols can be oxidized to aldehydes and carboxylic acids, while secondary alcohols can be oxidized to ketones. Tertiary alcohols are resistant to oxidation.

Dehydration: Alcohols can be dehydrated to form alkenes by heating them in the presence of an acid catalyst. The -OH group is removed as a water molecule.

Substitution: Alcohols can undergo substitution reactions, such as nucleophilic substitution and elimination reactions, to form different compounds.

4. Reactions of Alcohols Some of the important reactions of alcohols are:

a. Reaction with sodium: Alcohols react with sodium metal to form hydrogen gas and the corresponding alkoxide salt. b. Reaction with hydrogen halides: Alcohols react with hydrogen halides to form alkyl halides and water. c. Reaction with phosphorus halides: Alcohols react with phosphorus halides to form alkyl halides and phosphorus oxyhalides. d. Esterification: Alcohols react with carboxylic acids to form esters and water. e. Williamson synthesis: Alcohols react with alkyl halides to form ethers in the presence of a strong base.

These are some of the important topics related to alcohols that you will learn in the JEE (Main+Advance) intermediate course.

Nomenclature of JEE (Main+Advance) Intermediate Course Alcohols

The nomenclature of alcohols is an important topic covered in the JEE (Main+Advance) Intermediate Course on Alcohols. The International Union of Pure and Applied Chemistry (IUPAC) provides a systematic way to name alcohols based on the rules below:

1. Identify the longest carbon chain that contains the hydroxyl group (-OH) and name it as the parent chain. The suffix “-ol” is added to the parent chain name to indicate that it is an alcohol.
2. Number the carbon atoms in the parent chain starting from the end closest to the hydroxyl group. The hydroxyl group is assigned the lowest possible number.
3. If the parent chain contains a double bond, the suffix “-enol” is used instead of “-ol”. The double bond is assigned the lowest possible number.
4. If there are multiple hydroxyl groups, each one is numbered and named separately using a prefix such as “di” (two), “tri” (three), etc.
5. If there are substituents attached to the parent chain, they are named using the appropriate prefix and listed in alphabetical order before the parent chain name.
6. If there are multiple substituents, they are numbered and listed before the parent chain name. The substituent with the lowest possible number is given the lowest possible number.

Here are some examples of alcohol nomenclature using the IUPAC rules:

1. CH3CH2CH2OH: The longest carbon chain contains three carbons, so the parent chain is propane. The hydroxyl group is attached to the first carbon, so the name is 1-propanol.
2. CH3CH(OH)CH3: The longest carbon chain contains three carbons, so the parent chain is propane. The hydroxyl group is attached to the second carbon, so the name is 2-propanol.
3. CH3CH=CHCH2OH: The longest carbon chain contains four carbons, so the parent chain is butene. The hydroxyl group is attached to the fourth carbon, so the name is 4-butene-1-ol.
4. CH3CH(OH)CH(OH)CH3: The longest carbon chain contains four carbons, so the parent chain is butane. There are two hydroxyl groups attached to the second and third carbons, so the name is 2,3-butanediol.
