Q. 705.0( 6 Votes )

Which of the following hydrocarbons is unsaturated? C₃H₄; C₂H₆;

Class 10th Lakhmir Singh & Manjit Kaur - Chemistry 4. Carbon and Its Compounds

Answer :

C₂H₆ is a saturated hydrocarbon because if the number of hydrogen atoms is 2 more than double the number of carbon atoms, then it will be an alkane or saturated hydrocarbon. The general formula of alkane is C_nH_2n+2. Here, n is number of carbon atoms.

Thus, C₂H₆ (ethane) is a saturated hydrocarbon.

If the number of hydrogen atoms is 2 less than double the number of carbon atoms, then it will be an alkyne. The general formula of alkyne is C_nH_2n-2. Here, n is number of carbon atoms. Alkynes are unsaturated hydrocarbons.

Thus, C₃H₄ (Propyne) is an unsaturated hydrocarbon.
