(E)-1-(3-Bromo-phen-yl)-3-(4-ethoxy-phen-yl)prop-2-en-1-one
Abstract:
The title compound, C(17)H(15)BrO(2), adopts an E configuration. The dihedral angle between the two benzene rings is 10.09 (11)°. The enone plane makes dihedral angles of 12.05 (11) and 9.87 (11)°, respectively, with the bromo-phenyl and ethoxy-phenyl rings. The eth-oxy group is nearly coplanar with the attached benzene ring. In the crystal structure, the mol-ecules are linked by C-H⋯O hydrogen bonds, forming a zigzag ribbon-like structure along the b-axis direction.

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.

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.
As with other organic compounds, alcohols and phenols...
