N-(2,5-Dichloro-phen-yl)-4-methyl-benzene-sulfonamide
Abstract:
In the title compound, C(13)H(11)Cl(2)NO(2)S, the N-C bond in the C-SO(2)-NH-C segment has gauche torsion angles with respect to the S=O bonds. The mol-ecule is bent at the S atom with an C-SO(2)-NH-C torsion angle of 62.1 (2)°. Furthermore, the conformation of the N-H bond is syn to the ortho-chloro group in the adjacent benzene ring. The benzene rings are tilted by 67.8 (1)° relative to each other. The crystal structure features dimers linked by N-H⋯O hydrogen bonds. An intra-molecular N-H⋯Cl hydrogen bond is also observed.

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...
