Verified step by step guidance

Identify the molecular formula for each option. For example, the first option with 6 hydrogen atoms and 2 carbon atoms would be C2H6.

Determine the degree of unsaturation for each molecular formula. The degree of unsaturation indicates the number of rings and/or multiple bonds in a molecule.

Use the formula for degree of unsaturation: Degree of Unsaturation = (2C + 2 + N - H - X) / 2, where C is the number of carbons, N is the number of nitrogens, H is the number of hydrogens, and X is the number of halogens.

Apply the formula to each option. For example, for C2H6, the degree of unsaturation is (2*2 + 2 - 6) / 2 = 0, indicating no double bonds or rings.

Identify the option with a degree of unsaturation of at least 1, which indicates the presence of a carbon-carbon double bond. The correct option is the one with 6 hydrogen atoms and 3 carbon atoms, which has a degree of unsaturation of 1.
