Chemistry Worksheets Class 12 on Chapter 11 Alcohols, Phenols, and Ethers with Answers - Set 3

Alcohol, phenol, and ether are the categories of organic compounds that originate from the hydrocarbons. Alcohols are aliphatic hydrocarbons, in which the hydroxyl group replaces one of the hydrocarbon hydrogen atoms. It has a general formula ROH. At the same time, phenol is benzene, in which one of the benzene’s hydrogen is replaced by the hydroxyl group. It has a general formula of C6H5OH. In contrast, ether is the hydrocarbon in which the oxygen atom joins two alkyl groups.
