Concept explainers
(a)
Interpretation: Carbocation can rearrange to form a stable carbocation. The carbocation rearrangement with a curve arrow is to be interpreted for the given carbocation.
Concept introduction: Carbocation is an intermediate that carries a positive charge on the carbon atom. It tends to rearrange to form a more stable carbocation. The stability order of carbocation is:
Tertiary >Secondary >Primary
The notation to carbocation is given on the basis of the positive charge on the primary, secondary, and tertiary carbon atoms of the intermediate.
