Q.
Dow’s reaction involves
Alcohols Phenols and Ethers
Solution:
Dow's reaction involves alkaline hydrolysis of chlorobenzene.
$C _{6} H _{5} Cl +2 NaOH \xrightarrow[{\text { high pressure }}]{300^{\circ} C } C _{6} H _{5} ONa + NaCl + H _{2} O$
$2 C _{6} H _{5} ONa + H _{2} SO _{4} \longrightarrow 2 C _{6} H _{5} OH + Na _{2} SO _{4}$
This is an example of nucleophilic substitution reaction.
