Final answer:

The correct mechanism for the given SN1 reaction is 1) Nucleophilic attack followed by carbocation formation. In an SN1 reaction, the rate determining step involves formation of a carbocation intermediate. The nucleophile then attacks the carbocation to form the product. This mechanism is called SN1, which stands for substitution nucleophilic unimolecular.

Step-by-step explanation:

The correct mechanism for the given SN1 reaction is 1) Nucleophilic attack followed by carbocation formation.

In an SN1 reaction, the rate determining step involves formation of a carbocation intermediate. The nucleophile then attacks the carbocation to form the product.

This mechanism is called SN1, which stands for substitution nucleophilic unimolecular.
