Compure acetylene and benzene with respect to the following:
(a) hybridisation of carbon atoms and
(b) reaction with Bueyer's reagent.

Explanation

(a) In acetylene, both carbon atoms are sp hybridised, while in benzene all carbon atoms are `sp^2` hybridised.
(b) Acetylene decolourises pink colour of Baeyer.s reagent, but benzene does not.
Acetylene is oxidised by Baeyer.s reagent to give oxalic acid. `C_(2)H_(2)+4(O) overset(MnO_(4)^(-). OH^(-))to HOOC-COOH`
Benzene is not oxidised by Baeyer.s reagent.
