\text{O-H}
\][/tex]

A. The molecule has no nitrogen atoms.
B. The molecule contains no carbon double bonds.
C. The molecule contains a carbon-oxygen double bond.
D. The molecule has an OH group on the end.



Answer :

Final answer:

Saturated fats have no carbon-to-carbon double bonds, while unsaturated fats do. The given molecule is a saturated fat because it lacks double bonds.


Explanation:

Saturated fatty acids are those that contain no carbon-to-carbon double bonds (C=C). This means that each carbon atom in the chain is attached to the maximum number of hydrogen atoms.

For example, the molecule you provided, consisting of a chain of carbon atoms with hydrogen atoms attached and an -OH group at one end, demonstrates a structure typical of saturated fats.

Unsaturated fats, on the other hand, contain carbon-to-carbon double bonds, resulting in fewer attached hydrogen atoms and a different structure.
