Question

Q.9. Which of the following will show addition reaction : C4H10, C2H6, C2H4, CH4, C3H8?

Answer 1

The compounds which will undergo addition reaction are

Ethene C2H4 and

Propyne C3H4

This is because only alkenes and alkynes, being unsaturated hydrocarbons, undergo addition reactions, alkanes do not.

The other options given in the question namely C4H10, C2H6, and CH4 are alkanes and they are saturated hydrocarbons.

Thus they will not exhibit addition reactions.

Answer 2

The compounds which will undergo addition reaction are

Ethene C2H4 and

Propyne C3H4

This is because only alkenes and alkynes, being unsaturated hydrocarbons, undergo addition reactions, alkanes do not.

The other options given in the question namely C4H10, C2H6, and CH4 are alkanes and they are saturated hydrocarbons.
