Answer 2

Benzyl alcohol is an example of aromatic alcohol.

Explanation:

• The molecular formula of benzyl alcohol is $C_{6}H_{5}CH_{2}OH$. It is colourless with aromatic smell.
• The molecular weight of benzyl alcohol is 108 g/mol. Due to its polar nature, it used as a solvent. It is moderately soluble in water.
• Preparation
• It can be prepared from toluene(benzyl chloride). The reaction is:-
• $C_{6}H_{5}CH_{2}Cl + H_{2}O \longrightarrow C_{6}H_{5}CH_{2}OH + HCl$
• It can also be prepared through Grignard reaction using $C_{6}H{5}MgBr$ with suitable aldehyde or ketone.
• $HCHO + C_{6}H_{5}MgBr \xrightarrow{H_{2}O} C_{6}H_{6}CH_{2}OH + Mg(OH)Br$.
