Acetamide (source code)

= Acetamide

<Acetamide> is the <amide> $\mathrm{CH_3CONH_2}$. Donation of the nitrogen lone pair into the carbonyl system gives the carbon-nitrogen bond partial double-bond character.

This favors a relatively planar local geometry and reduces nitrogen basicity compared with a simple amine. Acetamide provides a small-molecule model for the electronic features of the <peptide bond>.
