Final answer:
The first step in drawing a mechanism for hydrohalogenation process with a carbocation rearrangement is the nucleophilic addition to the carbonyl group.
Step-by-step explanation:
The first step in drawing a mechanism for hydrohalogenation process with a carbocation rearrangement is the nucleophilic addition to the carbonyl group.
This step involves the nucleophile attacking the electrophilic carbon of a carbonyl compound.
For example, in the hydrohalogenation of an alkene, the nucleophile can be a halogen ion (X-). The carbonyl compound can be an aldehyde or a ketone.
