Some alkyl halides undergo substitution whereas some undergo elimination reaction on treatment with bases. Why?

Options

  1. AAll types of alkyl halides prefer to undergo substitution reaction.
  2. BTertiary alkyl halides prefer to undergo substitution reaction by S N 2 mechanism whereas primary halides unde
  3. CAll types of alkyl halides prefer to undergo elimination reaction.
  4. DPrimary alkyl halides prefer to undergo substitution reaction by S N 2 mechanism whereas tertiary halides unde

Correct answer

D. Primary alkyl halides prefer to undergo substitution reaction by S N 2 mechanism whereas tertiary halides unde

Step-by-step solution

Correct Option is : (D) Primary alkyl halides prefer to undergo substitution reaction by S N 2 mechanism whereas tertiary halides undergo elimination reaction due to the formation of stable carbocation.
