why are aromatic diazonium salts more stable than aliphatic diazonium salts?

Diazonium salts are prepared by diazotization reaction by the action of nitrous acid on cold solution of aromatic primary amine. Diazonium compounds can be converted by sand maeyers reaction to aryl halide. Aryl diazonium salts on ..

This is a convenient method of preparation of aryl cyanides only. It is not suitable for preparing alkyl cyanides because alkyl diazonium salts are quite unstable even at low temperatures. It involves the treatment of benzene diazonium salt with a mixtu..

Aryl diazonium salts constitute intermediates that can be used to synthesis many classes of organic compounds especially aryl halides in the pure stat..

The lattice energy determines the thermal stability of the salts. A higher lattice energy is generated when the ions are smaller and can more closely approach each other in the lattice. The greater the charge on the ions, the higher is the lattice energy as there is a larger attraction fo..

Hydrolysis of Aliphatic Nitro Compounds - Primary aliphatic nitro compounds can be converted to aldehydes by treatment of their carbanion salts with sulphuric acid. Secondary nitro alkanes hydrolyze with boiling HCl to give ketones and nitrous oxid..

Reaction with Nitrous Acid - The three classes of amines react differently with nitrous acid. Nitrous acid is a source of electrophilic nitrosonium ion (O = N + ), which reacts with amines. Nitrous acid being unstable is generated in situ from a mineral acid and sodium nitrite. Primary aromati..

>In non aqueous medium, the order of basic strength is 3 o > 2 o > 1 o . Aromatic amines are weaker bases as compared to ammonia. Electron releasing groups like - CH 3 , -OCH 3 , NH 2 etc., increase the basic strength while electron withdrawing groups like NO 2 , -CN etc decrease th..
