## Abstract The rates of reaction of 2‐, 3‐ and 4‐chloropyridine N‐oxides towards 1 M piperidine in methanol have been measured conductimetrically. Apparent unimolecular rate constants at 80°C are respectively 3,70.10^−4^, 1,04.10^−7^ and 1,02.10^−4^ sec^−1^. The reactivity sequence 2 > 4 >> 3 is d
