Question

Neopentyl alcohol reacts with HX according to ____________.

• A. $S_{N}1$ mechanism
• B. $S_{N}2$ mechanism
• C. $E2$ mechanism
• D. none of these

Answer 1

Answer: (A)

$S_{N}1$ mechanism

Neopentyl alcohol reacts with $HX$ according to $S_{N}1$ mechanism because on rearrangement it gives carbocation as an intermediate which is most stable carbocation. Hence, it follows $S{N}^1$ mechanism.
