Abstract:
In the title mol-ecule, C(17)H(13)FN(2)O(2), the 3,4-dihydro-pyrimidine ring adopts a flattened sofa conformation with the flap atom (which bears the fluoro-phenyl substituent) deviating from the plane defined by the remaining five ring atoms by 0.281 (2) Å. This plane forms dihedral angles of 85.98 (6) and 60.63 (6)° with the 4-fluoro-phenyl and benzoyl-phenyl rings, respectively. The dihedral angle between the 4-fluoro-phenyl group and the benzene ring is 71.78 (6)°. In the crystal, N-H⋯O hydrogen bonds link mol-ecules into inversion dimers that are further connected by another N-H⋯O inter-action into a two-dimensional supra-molecular structure parallel to (101).

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...
