Q. Assertion :Unsaturated hydrocarbons contain multiple bonds between the two

C -

atoms and show addition reactions. Reason: They also undergo many other chemical reactions that alkanes do not - the double bond in alkenes makes them more reactive than alkanes

Q. Give a chemical test to distinguish between:
(a) saturated and unsaturated compounds
(b) ethane and ethene
(c) ethene (ethylene) and ethyne (acetylene).
