4-{Eth-yl[(E)-4-(4-pyridylvin-yl)phenyl]-amino}benzaldehyde
Abstract:
In the title mol-ecule, C(22)H(20)N(2)O, the central aromatic ring forms dihedral angles of 45.30 (2) and 69.43 (2)°, respectively, with the outer pyridine and benzene rings. In the crystal structure, weak inter-molecular C-H⋯O inter-actions link the mol-ecules into layers parallel to the ab plane.

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.
