4-Chloro-N-(2,3-dimethyl-phen-yl)-2-methyl-benzene-sulfonamide
Abstract:
The asymmetric unit of the title compound, C(15)H(16)ClNO(2)S, contains two independent moleules. The conformation of the N-H bonds are anti to the ortho-methyl groups in the sulfonyl benzene rings of both the mol-ecules, while the N-H bonds are anti to the ortho- and meta-methyl groups in the aniline ring of one of the mol-ecules and syn in the other. Furthermore, the torsion angles of the C-SO(2)-NH-C segments in the two mol-ecules of are -66.8 (3) and 70.3 (3)°. The sulfonyl and the aniline benzene rings are oriented at angles of 44.1 (1) and 39.7 (1)° in the two mol-ecules. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into dimers.

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...
