Question

Choose the correct mechanism for the following SN1 reaction.

1) Nucleophilic attack followed by carbocation formation
2) Nucleophilic attack followed by carbocation rearrangement
3) Nucleophilic attack followed by concerted bond formation
4) Nucleophilic attack followed by concerted bond cleavage

Answer 1

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.
