Give the reagents and conditions necessary to prepare phenol from Benzene sulphonic acid.

Preparation of phenol from benzene sulphonic acid: Phenol is prepared from benzene sulphonic acid, when the benzene sulphonic acid is treated with the requisite quantity of soda as sodium carbonate or sodium hydroxide around the temperature of 350 ° C and then sodium phenoxide is formed. Then the sodium phenoxide is treated with Sulphuric acid and produces phenol.

Write IUPAC name of the following. CH 3 - CH | - CH | - CH 2 - OH OH CH 3

The first thing to keep in mind is to select the longest continuous chain. It contains four carbon atoms so the root word of the given compound is butane and the alcohol functional group is present, so the suffix is ‘ol’. The IUPAC name of the compound is 2 - Methyl - 1 , 3 - butanediol . CH 3 4 - CH | 3 - CH | 2 - CH 2 1 - OH OH CH 3
