Final answer:

The false statement is that to be enantiomers, a molecule must have at least three different atoms or groups connected to a central carbon; it should actually have four different groups attached. The question pertains to different types of isomers in chemistry.

Step-by-step explanation:

The subject of the question relates to isomers, which are compounds that have the same molecular formula but different structural formulas, leading to different properties.

Among isomers, there are several types, including structural isomers, geometric isomers (cis-trans isomers), and enantiomers.

Structural isomers have a different covalent arrangement of atoms, while geometric isomers have a different arrangement of atoms around a double bond.

Enantiomers, on the other hand, are stereoisomers that are nonsuperimposable mirror images of one another, and to qualify as enantiomers, a molecule should have at least four different atoms or groups connected to a central carbon atom.

With reference to the question provided, the false statement is option c. The correct answer is that to be enantiomers, a molecule must have at least four different atoms or groups connected to a central carbon, not just three.

Options a, b, and d are true statements. Structural isomers can indeed have the formulas CH3CH2COOH and C3H6O2, molecules require a double bond to be categorized as cis-trans isomers, and enantiomers must have four different groups attached to the central carbon.
