WebJan 29, 2024 · Benzene nucleus present in all the aromatic hydrocarbons is very stable; it gives a number of substitution reactions but resists addition reactions. Benzene also fails to give tests for unsaturation i.e. it does not decolourise alkaline KMnO4 and bromine water. WebQ.4 Benzene undergoes substitution reaction more easily than addition because: (A) It has a cyclic structure (B) It has three double bonds (C) It has six ... Although benzene contains three double bonds, normally it does not undergo addition reaction. (B) m-chlorobromobenzene is an isomer of m-bromochlorobenzene. ...
