Abstract:
The title compound C(12)H(17)N(3)O(2) (+)·Cl(-) consists of a discrete [NITpPyH](+) cation [NITpPy = 2-(4'-pyrid-yl)-4,4,5,5-tetra-methyl-imidazoline-1-oxyl-3-oxide] and a chloride anion. The NITpPy mol-ecule is protonated at the N atom of the pyridyl ring. The anions and cations are connected via N-H⋯Cl hydrogen bonds.

Acidity and Basicity of Alcohols and Phenols
Like water, alcohols are weak acids and bases. This is attributed to the polarization of the O–H bond making the hydrogen partially positive. Moreover, the electron pairs on the oxygen atom of alcohol make it both basic and nucleophilic. Protonation of an alcohol converts hydroxide, a poor leaving group, into water—a good one. The two acid–base equilibria corresponding to ethanol are depicted below.
Structure and Nomenclature of Epoxides
Cyclic ethers are heterocyclic compounds with an oxygen atom in the ring along with carbon atoms. They are named depending on the number of carbon atoms present in their ring system. Cyclic ethers with a three-membered ring system are called “oxirane”, four-membered ring systems as “oxetane”, five-membered ring systems as “oxolane”, and six-membered ring systems as “oxane”. The cyclic structure of these rings imposes angle strain, and this strain is more in the ring having a smaller number of...
