(E)-4-(4-Ethoxyphenyl)but-3-en-2-one

Abstract

In the title compound, C12H14O2, the benzene ring makes dihedral angles of 5.03 (8) and 5.37 (15)° with the mean planes of the but-3-en-2-one group and the ethoxy group, respectively. In the crystal, molecules are linked by two pairs of C—H...O hydrogen bonds forming inversion dimers, which enclose an R22(8) ring motif flanked by two R21(7) loops.
