Concept explainers
(a)
Interpretation: The increasing stability of carbocation is to be interpreted.
Concept introduction: Intermediates like carbocation can rearrange to give more stable carbocation. A primary carbocation carries a positive charge on the primary carbon atom whereas a secondary carbocation has a positive charge on the secondary carbon atom. Due to more hyperconjugation and inductive effect, the order of stability is:
Tertiary >Secondary >Primary
