Answer

Explanation:

Step1: Analyze reaction type

In the given reaction, HCN adds across the carbon - oxygen double bond of acetaldehyde ($H_3C - C=O$). The $H$ from $HCN$ adds to the oxygen and the $CN$ group adds to the carbon of the carbon - oxygen double bond.

Step2: Recall reaction definitions

Addition reactions involve adding atoms or groups to a multiple - bonded compound. Condensation reactions involve the loss of a small molecule like water. Elimination reactions form a multiple bond by removing atoms or groups. Substitution reactions replace one atom or group with another.
