Reaction of methyl bromide with aqueous sodium hydroxide involves
A)racemization
B)\[{{S}_{N}}1\] mechanism
C)retention of configuration
D)\[{{S}_{N}}2\] mechanism
Correct Answer:
D
Solution :
\[\xrightarrow{{}}HOC{{H}_{3}}+B{{r}^{-}}\]Since, the reaction rate depends upon the concentration of both reactant and nucleophile, it is a \[{{S}_{N}}2\] reaction. It involves inversion of configuration.
