Which of the following statements is correct for four isomeric bromobutanes?
View answer and explanation
Correct option: A
Of the two 1∘1^{\circ} bromides, the carbocation intermediate derived from (CH3)2CHCH2Br\left(\mathrm{CH}_3\right)_2 \mathrm{CHCH}_2 \mathrm{Br} is more stable than derived from CH3CH2CH2CH2Br\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{Br}
Option A (Of the two 1∘1^{\circ} bromides, the carbocation intermediate derived from (CH3)2CHCH2Br\left(CH_3\right)_2 CHCH_2 Br is more stable than derived from CH3CH2CH2CH2BrCH_3 CH_2 CH_2 CH_2 Br) is correct because the isopropyl group provides more hyperconjugative stabilization to the developing positive charge in the transition state compared to the n-propyl group.
