Pyridine Molecular Formula is C5H5N, its Hetrocyclic structure is similar to Benzene RING. Pyridine is an alkaline colorless, flammable liquid. Pyridine release unpleasant smell.
Properties: Pyridine is miscible with water It is a weak base It is highly flammable It has a distinctive, unpleasant fish-like smell
Uses: Pyridine is used as a solvent in organic chemistry and in industrial practice It is used to make medicines, vitamins, food flavorings, pesticides, paints, dyes, rubber products, adhesives, and waterproofing for fabrics
Pyridine is a reasonable nucleophile for carbonyl groups and is often used as a catalyst in acylation reactions. ... The nitrogen atom in pyridine is nucleophilic because the lone pair of electrons on nitrogen cannot be delocalised around the ring.
Pyridine is used as a polar, basic, low-reactive solvent, for example in Knoevenagel condensations. It is especially suitable for the dehalogenation, where it acts as the base of the elimination reaction and bonds the resulting hydrogen halide to form a pyridinium salt.
