Abstract:
In the title compound, C(17)H(18)NO(2) (+)·Cl(-)·H(2)O, a precursor to novel asymmetric catalysts, the N-containing six-membered ring of the tetra-hydro-quinolinium unit assumes a half-boat conformation. In the crystal, inter-molecular O-H⋯O, O-H⋯Cl, N-H⋯Cl and C-H⋯O hydrogen bonds and C-H⋯π inter-actions link the mol-ecules into a three-dimensional network.

01:11Nomenclature of Aromatic Compounds with Multiple Substituents
When more than one substituent is present on the benzene ring, the IUPAC nomenclature depends on the number of substituents present.
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...

02:45Alkyl 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...
