The Correct Option is A
Solution and Explanation
Step 1: But-2-ene is a symmetrical alkene.
Step 2: Electrophilic addition of $HCl$ will add $H$ to one carbon and $Cl$ to the other.
Step 3: Regardless of which carbon gets the $Cl$, the product is $CH_3 - CH_2 - CHCl - CH_3$, which is 2-chlorobutane.
