NEET Chemistry SN1 & SN2 Reactions MCQ Question
Which of the following statements is true regarding the stability of carbocation intermediates in SN1 reactions?
The carbocation from C6H5CH(C6H5)Br is more stable than from C6H5CH(CH3)Br due to resonance.
All carbocations are equally stable regardless of their structure.
The presence of a methyl group increases the stability of carbocations.
Carbocations are always less stable than their neutral counterparts.
Correct Answer
Detailed Explanation
The carbocation intermediate obtained from C6H5CH(C6H5)Br is more stable than that obtained from C6H5CH(CH3)Br because it is stabilised by two phenyl groups due to resonance, as mentioned in the context.
