Abstract:
In the title compound, C22H17FO2S, the dihedral angles between the mean plane [r.m.s. deviation = 0.005 (1) Å] of the benzo-furan ring system and the pendant 3-fluoro-phenyl and phenyl rings are 23.92 (5) and 32.44 (5)°, respectively. In the crystal, mol-ecules are linked by two weak C-H⋯O(sulfin-yl) hydrogen bonds and a C-H⋯π inter-action, forming a sheet, which lies in the ab plane. A π-π inter-action between the benzene and furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.976 (2) Å] links the mol-ecules into inversion dimers and connects adjacent sheets, resulting in a three-dimensional network.

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...

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and phenols...
