Ethylene is an unsaturated hydrocarbon which decolourises Br_(2)//C Cl – InterviewSolution

1.	Ethylene is an unsaturated hydrocarbon which decolourises Br_(2)//C Cl_(4) and alkaline KMnO_(4) solutions. In contrast, benzene is highly unsaturated yet it does not give the above reactions. This is because
Answer» ` Br_2//C Cl_4` and ALKALINE `KMnO_4` are MILD reagents all the carbon-carbon BOND lengths in benzene are equal benzene is stabilized by RESONANCE benzene is a PLANAR molecule. Solution :Benzene is stabilized by resonance.
