A saturated molecule is defined as?

A saturated molecule is defined as?

• A. A molecule with only single bonds
• B. A molecule with at least one double bond
• C. A molecule with a benzene ring
• D. A molecule with triple bonds

Answer: (A)

The concept being tested is saturation: a saturated molecule has as many hydrogen atoms as possible by bonding only with single bonds between carbon atoms. When a molecule has any multiple bonds (double or triple), or features like a benzene ring with delocalized double bonds, it is not saturated in simple terms. That’s why a molecule described as having only single bonds best matches the idea of saturation. If there’s a double or triple bond, fewer hydrogens can attach to the carbons, making the molecule unsaturated. So, the definition here is a molecule with only single bonds.
