Question

which of the following molecules would form hydrogen bonds? check all that apply. no₂ nh₃ h₂o hf ch₄

Explanation:

Hydrogen bonding occurs when a hydrogen atom is covalently bonded to a highly electronegative atom (such as N, O, or F).

• For \(NO_2\), there is no H atom bonded to N or O.
• For \(NH_3\), H is bonded to N (highly electronegative).
• For \(H_2O\), H is bonded to O (highly electronegative).
• For \(HF\), H is bonded to F (highly electronegative).
• For \(CH_4\), H is bonded to C (not highly electronegative enough for H - bonding).

Answer:

\(NH_3\), \(H_2O\), \(HF\)
