AMIDES AND RELATED FUNCTIONAL GROUPS
webhome.auburn.eduThe relatively low electrophilicity of amide carbonyl groups is reflected by their resistance to hydrolysis relative to functional groups such as esters. Recall that the presence of a carbonyl (C=O) and ether (O-C) dipole renders the "central" carbonyl carbon of an ester electron deficient; it is an electrophilic carbon atom.

www.cpp.eduwhat functional groups are present, but not always. The 1H and 13C NMR’s are often just as informative about functional groups, and sometimes even more so in this regard. Information obtained from one spectroscopic technique should be verified or expanded by consulting the other spectroscopic techniques.
