Assertion: The H-bonding of NH3\mathrm{NH}_3 and H2O\mathrm{H}_2 \mathrm{O} is represented as:
H−O∣H−−−H−N∣H−H{\text{H}} - \mathop {\text{O}}\limits_{\begin{array}{cccccccccccccccccccc} | \\ {\text{H}} \end{array}} - - - {\text{H}} - \mathop {\text{N}}\limits_{\begin{array}{cccccccccccccccccccc} | \\ {\text{H}} \end{array}} - {\text{H}}
Reason: H2O\mathrm{H}_2 \mathrm{O} is more acidic than NH3\mathrm{NH}_3 and thus, H2O\mathrm{H}_2 \mathrm{O} is a proton donor.
View answer and explanation
Correct option: B
Assertion is wrong but Reason is correct
Option A (Assertion is correct but Reason is wrong) is correct because the H-bonding representation is incorrect, and while water is more acidic than ammonia, it's not the primary reason for the specific H-bonding structure.
