The hybridisation of the carbon atoms in ethene and the bond angle about each are
- A. sp3 and 109.5 degrees
- B. sp and 180 degrees
- C. sp2 and 120 degrees
- D. sp2 and 109.5 degrees
Explanation
Each carbon forms three sigma bonds using sp2 hybrids arranged in a plane at 120 degrees, and the remaining unhybridised p orbitals overlap sideways to form the pi bond. That sideways overlap is what prevents rotation and makes geometric isomerism possible. The whole ethene molecule is therefore flat.
