When a cyanide ion attacks the carbonyl carbon of Propanal, what is the approximate bond angle around that carbon in the resulting intermediate?
Q1. When a cyanide ion attacks the carbonyl carbon of Propanal, what is the approximate bond angle around that carbon in the resulting intermediate?
Answer: 109.5 degrees
Explanation: In nucleophilic addition, the carbonyl carbon changes from sp2 (120 degrees) to sp3 (109.5 degrees). Option B represents the trigonal planar starting state.
