In which of the following compounds does hydrogen bonding contribute to the intermolecular forces? Yes CH3CHO No No Yes CHF2 PH3 HF No CH5N To have hydrogen bonding, you need a hydrogen bond donor (H bonded directly to O, N or F) and a hydrogen bond acceptor (O, N or F). If you have a donor (H-F, H-O, H-N), you will automatically have an acceptor (F, O, N) in that molecule. Submit Answer Incorrect.
