the hydrocarbons which undergo addition reaction are C3H6,C2H2
these hydrocarbons go addition reaction because these compounds have double and triple bonds which are needed to be converted into single bond and to do so addition reaction takes place...

Answer 2

|$\large\mathrm\purple{Solution}$|

Unsaturated hydrocarbons undergo addition reactions. C3H6 and C2H2 are unsaturated hydrocarbons which undergo addition reactions.
