Show Answer
Solution:
The compound is diethyl ether $(CH_3 CH_2)_2 O$ which is resistant to nucleophilic attack by hydroxyl ion due to absence of double or triple bond, whereas all other compounds given are saturated.
$ \begin{gathered} C_2 H_5 OC_2 H_5 \\ \underset{\text{ ether }}{ } \\ CH_3-C \equiv N \\ \text{ Acetonitrile } \end{gathered} $
$ \xrightarrow[\text{ Methyl acetate }]{\stackrel{O}{C}} \underset{\text{ ( }}{CH_3}-OCH_3 $
