$t$-butyl chloride preferably undergo hydrolysis by

• Correct answer
  A

  $\mathrm{S}_{\mathrm{N}} 1$ mechanism
• B

  $\mathrm{S}_{\mathrm{N}} 2$ mechanism
• C

  Any of (a) and (b)
• D

  None of these

Solution

Tertiary halide preferentially undergo $\mathrm{S}_{\mathrm{N}} 1$ substitution as they can give stable carbocation.

Hence, the correct answer is option: 'A'.
