N-(4-Chloro-benzo-yl)-2-methyl-benzene-sulfonamide
Abstract:
The asymmetric unit of the title compound, C(14)H(12)ClNO(3)S, contains two independent mol-ecules. The conformations of the N-C bonds in the C-SO(2)-NH-C(O) segments have gauche torsions with respect to the S=O bonds. The mol-ecules are twisted at the S atoms with torsion angles of -54.2 (2) and 63.8 (2)° in the two mol-ecules. The dihedral angles between the sulfonyl benzene rings and the -SO(2)-NH-C-O segments are 85.0 (1) and 87.0 (1)°. Furthermore, the dihedral angles between the sulfonyl and benzoyl benzene rings are 89.4 (1) and 82.4 (1)° in the two mol-ecules. In the crystal, mol-ecules are linked by N-H⋯O(S) hydrogen bonds.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
