Q. A hydrocarbon has the molecular formula $C_3H_4$.To find out whether it contains two double bonds of a triple bond, which of the following test should be performed

Hydrocarbons

Solution:

$CH_3C\equiv CH \xrightarrow[CuCl + NH_4OH]{} \underset{(\text{Red ppt})}{CH_3-C \equiv \overset{-}{C} Cu^+} \downarrow$
$CH_2 = C = CH_2 \xrightarrow[CuCl + NH_4OH]{}$ No reaction
Other reagent reacts with both the alkyne and diene.
