Q. Which of the following is least reactive towards $S_{N} 2$ mechanism?

$C H_{2} = C H - C H_{2} - Cl$

will be last reactive in $S_{N} 2$ reaction because the planar transition state involved in this case would be extremly unstable because of ring strain in three membered ring is very high.

Q. Which of the following is least reactive towards SN​2 mechanism?

CH2​=CH−CH2​−Cl

will be last reactive in SN​2 reaction because the planar transition state involved in this case would be extremly unstable because of ring strain in three membered ring is very high.
