<P> A hydrogen atom attached to a relatively electronegative atom will play the role of the hydrogen bond donor . This electronegative atom is usually fluorine , oxygen , or nitrogen . A hydrogen attached to carbon can also participate in hydrogen bonding when the carbon atom is bound to electronegative atoms , as is the case in chloroform , CHCl . An example of a hydrogen bond donor is the hydrogen from the hydroxyl group of ethanol , which is bonded to an oxygen . </P>
