(2E)-1-(2,6-Dichloro-3-fluoro-phen-yl)-3-(4-fluoro-phen-yl)prop-2-en-1-one
Abstract:
In the title compound, C(15)H(8)Cl(2)F(2)O, the C=C double bond is in the E configuration. In the cyrstal, C-H⋯O hydrogen bonds connect the mol-ecules into chains along the c axis. A π-π inter-action of 3.628 (1) Å is also observed between two polyhalogenated benzene rings. The dichloro-substituted ring exhibits partial disorder over two sets of sites, with site-occupancy factors of 0.573 (3) and 0.427 (3).

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.
