    Abstract:

    In the organic cation of the title compound, C(13)H(20)N(3) (+)·Cl(-)·H(2)O, the two pyrrolidine rings adopt twisted conformations. The pyridine ring makes dihedral angles of 14.57 (6) and 23.96 (6)° with the mean planes of the pyrrolidine rings. In the crystal structure, pairs of bifurcated inter-molecular O-H⋯Cl hydrogen bonds link the water mol-ecules and chloride anions into an R(4) (4)(8) ring motif. Inter-molecular N-H⋯Cl, C-H⋯Cl and C-H⋯O hydrogen bonds further inter-connect these rings with the organic cations into a two-dimensional network parallel to the bc plane.

    Ionic Compounds: Formulas and Nomenclature

    An element composed of atoms that readily lose electrons (a metal) can react with an element composed of atoms that readily gain electrons (a nonmetal) to produce ions through complete electron transfer. The compound formed by this transfer is stabilized by the electrostatic attractions (ionic bonds) between the oppositely charged ions.

    Aromatic Hydrocarbon Cations: Structural Overview

    Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic.

    Alkyl Halides

    Structural Properties
    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...
