Which of the following hydrogen bonds is likely to be the weakest?
- A \(\mathrm{C}-\mathrm{H} \cdots \mathrm{O}\)
- B \(\mathrm{N}-\mathrm{H} \cdots \mathrm{O}\)
- C \(\mathrm{O}-\mathrm{H} \cdots \mathrm{O}\)
- D \(\mathrm{O}-\mathrm{H} \cdots \mathrm{F}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{C}-\mathrm{H} \cdots \mathrm{O}\)
Step-by-step Solution
Detailed explanation
For \(x-\stackrel{\delta}{H}^{+} \cdots \stackrel{\delta-}{O}\) hydrogen bond; lower the electronegativity of \(x\); lower is the residual \(\delta+\) change induced on \(\mathrm{H}\) & hence a lesser electrostatic attraction is expected between \(\mathrm{H}\) & \(\mathrm{O}\);…
