1. React the carbonyl compound:
It is (circle one) CONJUGATED
NON-CONJUGATED
The Nucleophile is

Option 2: When Nu is a strong base (OH or OR),
1 (Preferred)
and the leaving group is identical to the Nu
2
NUB
Circle the option and reason
Option 1: Always use UNLESS
Option 2: (Remove the a H)
The Nu matches Y AND is -OR
2. Take care of the negative formal charge of the oxygen in the tetrahedral complex
Option 1 (Preferred): All cases except Option 2
1 (Preferred)
Option 2: If there are no leaving groups,
or if the only potential leaving group is
the Nu that was just added and it
is not a very good leaving group (N or O).
Circle the option and reason
Option 1: Always use UNLESS
Option 2: There is no leaving group (there are
only carbons and hydrogens), OR there are only
carbons and hydrogens except for the Nu that
just added, AND the Nu is N or O.
If the double bond is reformed, what criterion is used to select the leaving group? (circle one)
