Question:
The set of asymmetric top molecules is
The set of asymmetric top molecules is
Show Hint
Asymmetric top molecules have no symmetry in their moments of inertia, making their rotational spectra more complex than prolate or oblate molecules.

Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding asymmetric top molecules.
Asymmetric top molecules are those in which the three moments of inertia are all different. These molecules lack a plane of symmetry and have no special symmetry in their rotational properties.
Step 2: Analyzing the options.
- (D) CH\(_3\)OH, H\(_2\)O, and H\(_2\)CO are examples of asymmetric top molecules because they all have different moments of inertia.
- The other options contain molecules that either have a plane of symmetry or do not satisfy the condition of having three different moments of inertia.
Step 3: Conclusion.
The correct set of asymmetric top molecules is option (D).
Final Answer: \[ \boxed{\text{CH}_3\text{OH}, \, \text{H}_2\text{O}, \, \text{H}_2\text{CO}} \]
