Abstract:
The title compound, C19H16N2O, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. There is an intra-molecular O-H⋯N hydrogen bond in each mol-ecule with the phenol ring being inclined to the central benzene ring by 4.93 (14) and 7.12 (14)° in mol-ecules A and B, respectively. The conformation of the two mol-ecules differs essentially in the orientation of the terminal amino-phenyl ring with respect to the central benzene ring; this dihedral angle is 50.51 (4)° in mol-ecule A and 54.61 (14)° in mol-ecule B. The two outer aromatic rings are inclined to one another by 51.39 (14) and 49.88 (14)° in mol-ecules A and B, respectively. In the crystal, mol-ecules are connected by N-H⋯O hydrogen bonds generating -A-B-A-B- zigzag chains extending along [010]. The chains are linked via C-H⋯π inter-actions involving neighbouring A mol-ecules, forming slabs lying parallel to (100).

02:23Structure 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...

01:28Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the...
02:28Structure and Nomenclature of Ethers
Ethers are organic compounds with an ether functional group which is characterized by an oxygen atom connected to two — identical or different — alkyl, aryl, or vinyl groups. The C–O–C linkage in dimethyl ether — the simplest ether — has an approximately tetrahedral bond angle of 110.3 degrees. The oxygen atom is sp3- hybridized, with the C–O distance being about 140 pm.
