Question

The normal mode(s) of vibration of H\(_2\)O is/are: 

• A. A
• B. B
• C. C
• D. D

Hint:

For diatomic and polyatomic molecules like H\(_2\)O, consider both bending and stretching motions when analyzing vibrational modes.

Answer 1

The Correct Option is A, B, C

H\(_2\)O has two normal modes of vibration: 1. The bending mode, where the H-O-H bond angle changes. 2. The stretching mode, where the H atoms vibrate along the O-H bonds. Thus, the correct answer is (C) all of the above. Final Answer: (C) all of the above.
