Final answer:
The false statement is about enantiomers which requires four different atoms or groups attached to a chiral center, making option (c) incorrect as it only mentions three.
Step-by-step explanation:
The question pertains to the concept of structural isomers in chemistry, which are molecules with the same molecular formula but different structural arrangements of atoms. When considering the molecular formulas CH3CH2COOH and C3H6O2, these can indeed be structural isomers because they have the same molecular formula but can have different arrangements of the carbon chain and the functional groups, leading to different compounds.
The false statement in the given options would be one that does not adhere to the definitions and rules of isomerism, especially when it comes to defining geometric (cis-trans) isomers or enantiomers. Regarding enantiomers, the correct characterization is that they must have four different atoms or groups attached to a chiral center, making statement (c) the false one as it incorrectly states that there must be at least three different atoms or groups connected to a central carbon.
