  • question_answer
    Tertiary alkyl halides are practically inert substitution by \[{{S}_{N}}2\] mechanism because

    A) the carbocation formed is unstable

    B) is steric hindrance

    C) is inductive effect

    D) the rate of reaction is faster in  \[{{S}_{N}}2\] mechanism.

    Correct Answer: B

    Solution :

    In tertiary alkyl halides steric hindrance does not allow substitution by \[{{S}_{N}}2\] mechanism in which the nucleophile attacks on the carbon atom and the reaction takes place in single step.
