STANDARD Chemistry Sₙ2 Mechanism MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Tertiary alkyl halides are practically inert to substitution by Sₙ2 mechanism because
A
the carbocation formed is unstable
B
there is steric hindrance
C
there is inductive effect
D
the rate of reaction is faster in Sₙ2 mechanism.
Correct Answer
Option B
Detailed Explanation
In tertiary alkyl halides, steric hindrance does not allow substitution by Sₙ2 mechanism in which the nucleophile attacks on the carbon atom and the reaction takes place in single step.
