1,3-Diprop-2-ynyl-1H-imidazol-3-ium bromide
Abstract:
In the title salt, C(9)H(9)N(2) (+)·Br(-), the ethynyl groups are nearly anti-parallel to each other [the angle between the two ethynyl groups is179.7 (2)°]. No classical hydrogen bonds or π-π inter-actions are observed. The mol-ecules are linked by C-H⋯Br hydrogen bonds. The bromide anions are involved in inter-actions with three H atoms.

Halogenation of Alkenes
Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
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...
