Answer:
Cyanohydrin
Explanation:
Step 1:
The nucleophilic C in the cyanide adds to the electrophilic C in the polar carbonyl group, electrons from the C=O move to the electronegative O creating an intermediate alkoxide
Step 2:
An acid/base reaction. Protonation of the alkoxide oxygen creates the cyanohydrin product.
