Question

State symmetry elenents present in water and ammonia

Answer 1

Answer:

The NH3 molecule belongs to the C3v group as it has the symmetry elements E, C3, and three σv planes. All heteroatomic diatomic molecules and OCS belong to the group C∞v because all rotations around the internuclear axis and all reflections across the axis are symmetry operations.

I hope this will help

Answer 2

Explanation:

The point group symmetry of a molecule can be described by 5 types of symmetry element. results in a molecule indistinguishable from the original. This is also called an n-fold rotational axis and abbreviated Cn. Examples are the C2 axis in water and the C3 axis in ammonia.
