In a nucleophilic substitution reaction : $R - Br + {Cl}^{-} \overset{DMF}{⟶} R - Cl + {Br}^{-}$ , which one of the following undergoes complete inversion of configuration ?

Options:

Answer:

Solution:

In $S_{N} 2$ (nucleophilic bimolecular substitution) inversion takes place

$S_{N} 2 \propto \frac{1}{stearic hindrance}$

Rate of R–X is 1° > 2° > 3°
