Question

Which one is most reactive towards S_N 1 reactions?

• A. $C_6{H}_{5}CH\left(C_6{H}_5\right)Br$
• B. $C_6{H}_{5}CH\left(C{H}_3\right)Br$
• C. $C_6{H}_{5}C\left(C{H}_3\right)\left(C_6{H}_5\right)Br$
• D. $C_6{H}_{5}C{H}_{2}Br$

Answer 1

The correct option is C $C_6{H}_{5}C\left(C{H}_3\right)\left(C_6{H}_5\right)Br$

1)(c) Most stable carbocation formation by halide shows more reactivity for S_N 1 reactions.
