Question

What is wrong with the following mechanism?

1) There is no leaving group, so there should be no arrows.
2) The arrow should be removing a proton from the H₂O group.
3) An arrow is also needed to indicate the loss of the leaving group.
4) The arrow is backwards.

Answer 1

The given mechanism has multiple issues: no leaving group, incorrect arrow placement and direction. These errors need to be corrected.

Step-by-step explanation:

The main issues with the given mechanism are:

1. There is no leaving group, so there should be no arrows.
2. The arrow should be removing a proton from the H2O group.
3. An arrow is also needed to indicate the loss of the leaving group.
4. The arrow is backwards.

These errors should be corrected to properly represent the mechanism.
