What is the expected geometry of CH3-NH-CH3?(a) Square planar(b) Trigo

1.	What is the expected geometry of CH3-NH-CH3?(a) Square planar(b) Trigonal planar(c) Trigonal pyramidal(d) Trigonal bipyramidalThe question was posed to me during an internship interview.This intriguing question originated from Structure of Amines in portion Amines of Chemistry – Class 12
Answer» Correct choice is (c) 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.
