प्रश्न
Which of the following hydrocarbons is unsaturated?
C3H4; C2H6
उत्तर
C3H4 (CnH2n-2) is an unsaturated hydrocarbon. It has three carbon atoms, of which two carbon atoms are connected by a triple bond. Here, n is 3. Now, substituting n in the formula of the alkynes, we get, `C_3H_(2-3-2)= C_3H_4` .This compound is called propyne. C2H6 is a saturated hydrocarbon with two carbon atoms bonded by a single bond.
