a) HF is a weak acid neutralized by NaOH: This is an acid-base reaction and has no relation with hydrogen bonding.
b) HF has a higher boiling point than HCl: This happens due to hydrogen bonding. Due to smaller size of fluorine HF shows greater hydrogen bonding than HCl.
c) CH4 molecules interact more closely in the liquid than in the gas phase: CH4 can not form hydrogen bonding. Because a hydrogen bond is the electrostatic attraction between polar molecules that occurs when a hydrogen (H) atom bound to a highly electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F) experiences attraction to some other nearby highly electronegative atom.
d) Ice, H2O, has a solid structure with alternating H2O interactions: Water hydrogen bonds very well, and that's why it forms such an ordered structure in the solid phase.
e) H2Te has a higher boiling point than H2S:
Aa hydrogen bonding only occurs with N-H, O-H, and H-F bonds.
The reason that H2Te boils at a higher temperature than H2S is
simply because it's heavier.
