Question:
Which of the following is more reactive towards \(S_N1\) reaction: 2-bromo-2-methylbutane or 1-bromopentane?
Which of the following is more reactive towards \(S_N1\) reaction: 2-bromo-2-methylbutane or 1-bromopentane?
Show Hint
SN1 reactivity: 3°>2°>1° due to carbocation stability.

Solution and Explanation
\(S_N1\) reactions proceed via carbocation formation. Stability of carbocation determines reactivity.
- 2-bromo-2-methylbutane → forms tertiary carbocation
- 1-bromopentane → forms primary carbocation
