Question

Identify the sequence of curved arrows (electron movement) in the steps of the following reaction.

1) Proton transfer, proton transfer, nucleophilic Attack
2) Proton transfer, loss of leaving group
3) Nucleophilic attack, proton transfer, loss of leaving group
4) Proton transfer, nucleophilic attack, proton transfer

Answer 1

The correct sequence of curved arrows in the steps of the reaction is proton transfer, nucleophilic attack, proton transfer, loss of leaving group.

Step-by-step explanation:

The correct sequence of curved arrows (electron movement) in the steps of the given reaction is:

1. Proton transfer
2. Nucleophilic attack
3. Proton transfer
4. Loss of leaving group

First, there is a proton transfer, followed by a nucleophilic attack. Then, there is another proton transfer, and finally, the leaving group is lost. This sequence of steps is represented by the curved arrows.
