Question:
Which of the following compounds will not absorb UV radiation?
Which of the following compounds will not absorb UV radiation?
Show Hint
Molecules with conjugated systems absorb UV radiation due to electronic transitions between molecular orbitals.
Updated On: Jun 8, 2025
- \( \text{Chloral hydrate} \)
- \( \text{Salicylic acid} \)
- \( \text{Acetanilide} \)
- \( \text{Chloramphenicol} \)
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Chloral hydrate lacks conjugated pi bonds, preventing UV absorption.
Compounds like salicylic acid, acetanilide, and chloramphenicol possess aromatic rings, which strongly absorb UV radiation.
UV spectroscopy is widely used to study molecular conjugation and electronic transitions.
