Write a short note on Hofmann elimination
Advertisements
उत्तर
When tetraalkylammonium halide is heated with moist silver oxide, it gives quaternary ammonium hydroxide which is a deliquescent crystalline solid, and strongly basic like NaOH or KOH.
Quaternary ammonium hydroxides on strong heating undergo b-elimination to give an alkene, the reaction is called Hofmann elimination. The least substituted alkene is obtained as a major product (in contrast to Saytzeff elimination).
