MCQ
What is the expected geometry of CH3 - NH - CH3?
- ASquare planar
- BTrigonal planar
- CTrigonal pyramidal
- DTrigonal bipyramidal
✓
Answer
- Trigonal pyramidal
Explanation:
CH3 - NH - CH3 is an amine in which two hydrogen atoms are replaced by methyl groups.
The hybridisation of N atom of amines is same as that of ammonia, and is also expected to have a pyramidal geometry, with N at the apex and the groups CH3, H and CH3 occupying the corners of a trigonal base.
