Here are the essential concepts you must grasp in order to answer the question correctly.
Molecular Formula and Structural Isomers
The molecular formula C6H12 indicates a compound with six carbon atoms and twelve hydrogen atoms. Understanding structural isomers is crucial, as these compounds can have different arrangements of atoms, leading to distinct structures with the same formula. Isomers can include linear chains, branched chains, rings, and those with double bonds, affecting the compound's properties.

Elements of Unsaturation
Elements of unsaturation refer to the presence of pi bonds or rings in a molecule, which reduce the number of hydrogen atoms compared to a saturated hydrocarbon. The formula 1/2(2C + 2 - H) calculates the degree of unsaturation, helping identify the presence of double bonds or rings. For C6H12, the degree of unsaturation is one, indicating either one double bond or one ring.

Cycloalkanes and Alkenes
Cycloalkanes are hydrocarbons containing carbon atoms arranged in a ring, while alkenes are hydrocarbons with at least one carbon-carbon double bond. Both types of compounds can be derived from C6H12, with cyclohexane as a ring example and hexene as a double bond example. Understanding these structures is essential for identifying possible isomers of C6H12 that meet the question's criteria.
