Question

Question 9.14 Among NH3, H2O and HF, which would you expect to have highest magnitude of hydrogen bonding and why?

Class XI Hydrogen Page 289

Answer 1

A small and highly electronegativity elements form a stronger hydrogen bond. The order of size of N , O and F is F < O < N .and so the order of strength of hydrogen bond is F > O > N.

Hence, electronegativity of F is the highest, therefore magnitude of positive charge on hydrogen and negative charge on F is the highest in HF and Hence, electrostatic attraction of H bonding is the strongest in HF.
