(E)-1-(1-Benzyl-5-methyl-1H-1,2,3-triazol-4-yl)-3-phenyl-prop-2-en-1-one
Abstract:
The asymmetric unit of the title compound, C(19)H(17)N(3)O, contains two independent mol-ecules. In one mol-ecule, the essentially planar triazole ring [maximum deviation = 0.003 (2) Å] forms dihedral angles of 5.57 (12) and 87.51 (12)° with the two phenyl rings, while in the other mol-ecule [maximum deviation in triazole ring = 0.001 (2) Å] these angles are 1.55 (10) and 82.73 (11)°. The dihedral angles between the two phenyl rings in the two mol-ecules are 87.77 (13) and 81.22 (11)°. In the crystal, the independent mol-ecules are connected via a weak C-H⋯N hydrogen bond, forming dimers. Further stabilization is provided by weak C-H⋯π inter-actions.

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...
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...
