what functional groups are good hydrogen bond donors
Any functional group that has these can hydrogen-bond with neighboring molecules: 1  C=O (hydrogen-bond acceptor) 2  CâOâC (hydrogen-bond acceptor) [some] 3  CâNR (hydrogen-bond acceptor) 4  C=NR (hydrogen-bond acceptor) 5  CâOH (hydrogen-bond donor AND acceptor) 6  CâNH (hydrogen-bond donor AND acceptor) 7  C=NH (hydrogen-bond acceptor AND donor)
