The shape around the carbonyl group is described as:
ALinear and long
BOctahedral form
CTrigonal coplanar
DTetrahedral solid
Answer & Solution
Correct answer: C. Trigonal coplanar
1. The carbon has three neighbours, all in one plane.
2. The angles between them are near 120 degrees.
3. That arrangement is called trigonal coplanar.
