Consider the reaction.

 

Complete the electron‑pushing mechanism for the reaction by drawing the necessary organic structures and curved arrows for each step. Make sure to include all nonbonding electron pairs. (Having trouble frawing the final product!)

 
Consider the reaction.

A five-membered cyclic structure with an oxygen atom double-bonded to a carbon (a carbonyl group) is shown, with lone pairs on the oxygen.

Reagents:
1. NaBH₄
2. D₂O

Instructions:
Complete the electron-pushing mechanism for the reaction by drawing the necessary organic structures and curved arrows for each step. Make sure to include all nonbonding electron pairs.

Explanation:
This reaction appears to involve the reduction of a carbonyl group to an alcohol using sodium borohydride (NaBH₄), followed by deuteration with deuterium oxide (D₂O). The mechanism should illustrate the hydride transfer from NaBH₄ to the carbon of the carbonyl group, with subsequent protonation by D₂O.
