On mixing ethyl acetate with aqueous sodium chloride, the composition of the resultant solution is

(A) $CH_{3} COOC_{2} H_{5} + NaCl$ ✓ Correct
(B) $CH_{3} Cl + C_{2} H_{5} COONa$
(C) $CH_{3} COCl + C_{2} H_{5} OH + NaOH$
(D) $CH_{3} COONa + C_{2} H_{5} OH$

Answer: (A)

Solution

Ethyl acetate is an ester that neither mixes with nor reacts with aqueous sodium chloride; chloride is far too weak a nucleophile to displace the ethoxy group, and nothing drives any exchange. So no reaction takes place, and the mixture simply holds the ester

CH X_{3} COOC X_{2} H X_{5}

alongside the

NaCl

it was combined with.
