(4-But-oxy-phen-yl)(1H-pyrrol-2-yl)methanone
Abstract:
The asymmetric unit of the title compound, C(15)H(17)NO(2), contains two independent mol-ecules in which the dihedral angles between the pyrrole and benzene rings are 42.43 (9) and 45.70 (9)°. In both mol-ecules, the but-oxy chains are disordered over two sets of sites, with occupancy ratios of 0.701 (7):0.299 (7) and 0.869 (4):0.131 (4). Each mol-ecule forms a dimer with an inversion-related mol-ecule, through a pair of N-H⋯O hydrogen bonds. Weak C-H⋯O inter-actions link these dimers in the crystal structure.

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.

Structure 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.
Classification of Ethers
Based on their attached substituent groups, ethers can be classified into two...
