Which formula represents an unsaturated hydrocarbon?
(1) C2H6 (3) C5H8
(2) C3H8 (4) C6H14

The answer is (3) C5H8. The unsaturated hydrocarbon has double bonds between carbon atoms. And there is a rule of formula that if the carbon number *2 + 2 = hydrogen number, then it is saturated hydrocarbon.

Answer: The correct answer is Option 3.

Explanation:

Saturated hydrocarbons are defined as the hydrocarbons which have single covalent C-C bonds. They are known as alkanes. The general formula for these hydrocarbons is [tex]C_nH_{2n+2}[/tex]

Unsaturated hydrocarbons are defined as the hydrocarbons which have double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is [tex]C_nH_{2n}[/tex] and [tex]C_nH_{2n-2}[/tex]

For the given options:

Option 1: [tex]C_2H_6[/tex]

This is a saturated hydrocarbon where n = 2.

Option 2: [tex]C_3H_8[/tex]

This is a saturated hydrocarbon where n = 3.

Option 3: [tex]C_5H_8[/tex]

This is an unsaturated hydrocarbon where n = 5. It is an alkyne.

Option 4: [tex]C_6H_{14}[/tex]

This is a saturated hydrocarbon where n = 6.

Hence, the correct answer is Option 3.
