Question

Which of the following structural isomers of compound $C_4{H}_{9}Br$ is most reactive towards $S_{N}1$ reaction ?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

The isomer of compound $C_4{H}_{9}Br$ which is most reactive towards $S_{N}1$ reaction is tertbutylbromide. In general, tertiary alkyl halides can form the most stable carbocation. Hence, reacts faster in $S_{N}1$ reaction. Therefore, the correct answer is option (c).
