Assetion(A): Acetylene on additionalpolymerization gives benzene. Reason(R): The empirical formulae of acetylene and benzene are same The correct answer is

Answer»

Both (A) and (R ) are TRUE and (R ) is the CORRECT explanation of (A)
Both (A) and (R ) are true and (R ) is not the correct explanation of (A)
(A) is true but (R ) is false
(A) is false but (R ) is true

Solution :`underset("ACETYLENE")(3C_(2)H_(2))underset("trimerisation")overset("Red hot metallic tube")rarrunderset("Benzene")(C_(6)H_(6))`
Empirical FORMULA acetylene = CH
Empirical formula of benzene = CH
