Question

draw the simplest possible set of curved arrows that shows how the structure on the left could be turned into the structure on the right.

Explanation:

Step1: Move lone - pair from N

A lone - pair of electrons on the nitrogen atom moves to form a double - bond between N and C.

Step2: Break C - O single bond

The electrons in the C - O single bond move onto the oxygen atom.

Answer:

1. Draw an arrow from the lone - pair on N to the C atom to form a double - bond.
2. Draw an arrow from the C - O bond towards the O atom to give the O atom a lone - pair and a negative charge.
