Which from the following molecules does not develop intermolecular hydrogen bonding?
Options
- AH ₂ O
- BNH ₃
- CBr ₂
- DHF
Correct answer
A. H ₂ O
Step-by-step solution
Intermolecular hydrogen bonding requires hydrogen atoms covalently bonded to highly electronegative atoms (F, O, or N) adjacent to atoms with lone electron pairs. Water ( H ₂ O ) features hydrogen-oxygen bonds with oxygen lone pairs, enabling hydrogen bonding. Ammonia ( NH ₃ ) has hydrogen-nitrogen bonds with nitrogen lone pairs, facilitating hydrogen bonding. Hydrogen fluoride (HF) contains hydrogen-fluorine bonds with fluorine lone pairs, supporting strong hydrogen bonding. Bromine ( Br ₂ ) lacks hydrogen atoms e
