2-[4-(2-Methyl-prop-yl)phen-yl]-N'-[(E)-1-phenyl-ethyl-idene]propane-hydrazide
Abstract:
In the title compound, C(21)H(26)N(2)O, the dihedral angle between the two aromatic rings is 85.90 (19)°. The propenone-hydrazide unit forms dihedral angles of 21.62 (8) and 72.83 (9)°, respectively, with the terminal and central aromatic rings. The 2-methyl-propyl group is disordered over two sites, with occupancies of 0.533 (13) and 0.467 (13). In crystal structure, mol-ecules are linked into centrosymmetric dimers by paired N-H⋯O and C-H⋯O hydrogen bonds. In addition, C-H⋯π inter-actions are 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.
