WebAzo coupling. In organic chemistry, an azo coupling is an organic reaction between a diazonium compound ( R−N≡N+) and another aromatic compound that produces an azo … WebAnswer: Diazo Compounds are Compounds containing -N=N- group which are known as diazo compounds. Their general structure is R-N=N-R’ Here R and R’ are preferably arene groups and the azo group is thus stabilised by becoming part of extended delocalised system. They are prepared by coupling reacti...
