Write the symmetry elements and the point groups of the following:

(i) Water (ii) Ammonia (iii) Benzene

(i) Water (H₂O):  
Water has a bent molecular structure with an angle of approximately 104.5°. The symmetry elements in water are:

- E (Identity element): Present in all molecules.
- C₂ (Twofold rotation axis): The molecule has a C₂ axis passing through the oxygen atom and bisecting the H-O-H angle.
- σv (Vertical mirror plane): There are two mirror planes in water, each containing the C₂ axis and passing through the H atoms.
- i (Inversion center): Water does not possess an inversion center.

Water belongs to the C₂v point group, _________ _____ ________ _____ _____ ________ ____.
