By $(ii)$ reaction

Vedclass · Answer

(B) Reaction $(i)$ involves the hydrolysis of ethyl bromide with water,which is a slow reversible reaction and produces $HBr$,which can push the equilibrium backward.Reaction $(ii)$ uses moist silver oxide $(Ag_2O + H_2O \longrightarrow 2AgOH)$. The $AgOH$ reacts with $CH_3CH_2Br$ to form $CH_3CH_2OH$ and $AgBr$. The precipitation of $AgBr$ drives the reaction to completion,making it a much more efficient and easier method for the preparation of ethanol.

Ethanol can be prepared more easily by which reaction?
$(i) \ CH_3CH_2Br + H_2O \longrightarrow CH_3CH_2OH + HBr$
$(ii) \ CH_3CH_2Br + Ag_2O \text{ (moist)} \longrightarrow CH_3CH_2OH + AgBr$
