II$.$ Working backwards to the original carbonyl compound and Grignard Reagent.

Worked Example

Look at the carbon where the $OH$ group is bonded and sever the bond between it and the next$-$

door neighbor carbon. The side of this bond with the $OH$ group was the original carbonyl

compound, and the other side was the Grignard.
