Concept explainers

Diol

In chemistry there are so many chemical compounds that have a hydroxyl group but a chemical compound having two hydroxyl groups (-OH) is termed as a diol. It also implies the presence of two alcohols whereas polyols contain two or more than two hydroxyl groups (-OH). Glycol or 1,2-diol is an aliphatic diol that has two alcohol groups on adjacent carbon atoms. In industries, the most commonly used diol is ethylene glycol.

1. Dehydration: 2. Oxidation: This is a reaction where an alcohol loses a water molecule to form an alkene. For example, when ethanol is treated with an acidic catalyst, such as sulfuric acid, it undergoes dehydration to form ethene (CH2=CH2) and water. ALCOHOLS In this reaction, an alcohol is converted to either a carbonyl compound or a carboxylic acid. 3. Esterification: Types of Reaction (s) For example, primary alcohols can be oxidized to aldehydes or carboxylic acids, while secondary alcohols can be oxidized to ketones. Tertiary alcohols are usually not affected by oxidations 4. Substitution: The conversion of an alcohol and a carboxylic acid to an ester and water, in the presence of an acid catalyst.
