Tertiary alkyl halide is practically to substitution by \( S_{N} 2 \) mechanism because of
- A Insolubility
- B Instability
- C Inductive efffect
- D Steric hindrance
Answer & Solution
Correct Answer
(D) Steric hindrance
Step-by-step Solution
Detailed explanation
In \( S_{N} 2 \) reactions, nucleophile approach to the carbon bearing the leaving group, the presence of bulky substituents
inhibits the incoming nucleophile which decrease the rate of reaction, therefore, alkyl halides having bulkier substituents
or higher degree alkyl halides preferably react through \( S N_{1} \) path. The order of reactivity for \( S_{N} 1 \) path is \( 1^{\circ}>2^{\circ}>3 \)
