Hydrogen BondMediumQuestion 600321

Question

Hydrogen bonding occurs between F, O, N because these atoms are:
  1. A
    Large and electronegative
  2. B
    Small and highly electronegative with lone pairs
    Correct
  3. C
    Radioactive
  4. D
    Metals

Correct answer

Small and highly electronegative with lone pairs

Explanation

H-bonding requires: (1) H bonded to a small, highly electronegative atom (F, O, N), (2) lone pair on acceptor atom. The small size allows close approach for electrostatic interaction.
