2-Methyl-1H-benzimidazol-3-ium hydrogen phthalate
Abstract:
The asymmetric unit of the title compound, C(8)H(9)N(2) (+)·C(8)H(5)O(4) (-), contains two independent ion pairs. In each 2-methyl-1H-benzimidazolium ion, an intra-molecular O-H⋯O bond forms an S(7) graph-set motif. In the crystal, the components are linked by N-H⋯O hydrogen bonds, forming chains along [210]. Further stabilization is provided by weak C-H⋯O hydrogen bonds.

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
