Part B H Transfer Reactions

Hydrogen bonds will normally form only between a [lone pair on N, O, or F] and an [H on N, O, or X] For example  

(E) According to the rules in Model 6, is the dotted line marked with an X a hydrogen bond  

Construct an explanation for why an H attached to an N or O atom can participate in a hydrogen bond (H-bond) while an H attached to a carbon atom cannot. 

Circle each molecule below that you expect to be capable of hydrogen bonding to itself 

An hydrogen-bond donor has an H suitable for hydrogen bonding. An hydrogen-bond acceptor has a lone pair suitable for hydrogen bonding.
