Question:
The most convenient spectroscopic technique to establish the presence of intermolecular hydrogen bonding is:
The most convenient spectroscopic technique to establish the presence of intermolecular hydrogen bonding is:
Show Hint
Think about which technique directly measures bond stretching frequencies.
Updated On: Jul 3, 2026
- UV
- IR
- NMR
- None of the above
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: H-bonding weakens X-H bond, changing force constant.
Step 2: IR probes vibrational transitions, directly detecting X-H stretching frequency change.
Step 3: UV probes electronic transitions, not sensitive to this.
