3-Chloro-N-(4-meth-oxy-phen-yl)propanamide

Abstract

The title compound, C(10)H(12)ClNO(2), is a halogenated derivative of a secondary amide bearing an aromatic substituent. The C(=O)-N(H)-C(ar)-C(ar) torsion angle of -33.70 (18)° rules out the presence of resonance spanning the amide as well as the aromatic system. In the crystal, classical N-H⋯O hydrogen bonds, as well as C-H⋯O contacts connect the mol-ecules into chains propagating along the a axis.
