Which one of the following alkenes when treated

Question:

Which one of the following alkenes when treated with HCl yields majorly an anti Markovnikov product?

  1. $\mathrm{F}_{3} \mathrm{C}-\mathrm{CH}=\mathrm{CH}_{2}$

  2. $\mathrm{Cl}-\mathrm{CH}=\mathrm{CH}_{2}$

  3. $\mathrm{CH}_{3} \mathrm{O}-\mathrm{CH}=\mathrm{CH}_{2}$

  4. $\mathrm{H}_{2} \mathrm{~N}-\mathrm{CH}=\mathrm{CH}_{2}$


Correct Option: 1

Solution:

Due to higher $\mathrm{e}^{-}$withdrawing nature of $\mathrm{CF}_{3}$ group.

It follow anti markovnikoff product
