What is the order of ease of dehydrohalogenation of alkyl halides?

Options

  1. A3^ 2^ 1^
  2. B2^ 1^ 3^
  3. C3^ 1^ 2^
  4. D1^ 2^ 3^

Correct answer

A. 3^ 2^ 1^

Step-by-step solution

According to Saytzeff elimination, the ease of dehydrohalogenation depends on the stability of the alkyl substituted alkenes which is given as, R ₂ C = CR ₂ R ₂ C = CHR R ₂ C = CH ₂, RCH = CHR RCH = CH ₂ The ease of , -dehydrohalogenation is: 3^ 2^ 1^
