Abstract:
The title compound, C14H9Br2N3O·0.5C2H5OH, crystallizes with two 2-[(1H-benzimidazol-2-yl)imino-meth-yl]-4,6-dibromo-phenol mol-ecules and one ethanol solvent mol-ecule in the asymmetric unit. The benzene and benzimidazole rings subtend dihedral angles of 4.5 (3) and 5.2 (2)° in the two mol-ecules. In the crystal, one mol-ecule presents π-π stacking with the equivalent mol-ecule related by inversion, at a distance of 3.30 Å (separation between mol-ecular mean planes). A three-dimensional network is formed through N-H⋯N, N-H⋯O and O-H⋯N hydrogen bonds.

Acidity and Basicity of Alcohols and Phenols
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.

Physical Properties of Ethers
An ether molecule has a net dipole moment due to the polarity of C–O bonds. Subsequently, boiling points of ethers are lower than those of alcohols of comparable molecular weight and slightly higher than those of hydrocarbons of comparable molecular weight (Table 1).
Ethers can act as hydrogen bond acceptors, making them more water-soluble than hydrocarbons, but since ethers cannot act as hydrogen bond donors, they are much less soluble in water than alcohols. Ethers are considered...
