Abstract:
In the title compound, C29H23ClN2O, the 5-chloro-phenol ring and the imidazole ring are nearly coplanar, with a dihedral angle of 15.76 (9)° between them. The ethyl-phenyl ring and the two phenyl rings subtend angles of 71.09 (7), 43.95 (5) and 36.53 (9)°, respectively, with the imidazole plane. An intra-molecular O-H⋯N hydrogen bond supports the mol-ecular conformation, and an inter-molecular C-H⋯O inter-action, originating from an ortho-phenyl H atom, stabilizes the packing arrangement. In addition, a weak C-H⋯π inter-action, also involving an ortho-phenyl H atom, is observed.

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.
