Question

the symmetry elements not belong to nh3 molecule (1) inversion (2) c2(3) C3(4) sigmav*
​

Answer 1

Explanation:

The symmetry elements of NH3 are E, 2C3, and 3 sigma-v. To elaborate, the molecule is of C3v symmetry with a C3 principal axis of rotation and 3 vertical planes of symmetry

Answer 2

Inversion does not belong to ammonia.

• The shape of the ammonia molecule is pyramidal.
• It has a C3 axis through which it can rotate and give an identical structure.
• It has a three C2 axis through which it can rotate and give an identical structure.
• It has three-sigma v passes through the N-H bond.
• It has no centre of inversion.
• Hence the correct option is 1.
