what best describes these three molecules?\nthey are not isomers.\nthey are structural isomers.\nthey are geometric isomers.\nthey are both structural and geometric isomers.
Answer
Brief Explanations:
Structural isomers have the same molecular formula but different structural arrangements of atoms. Geometric isomers involve different spatial arrangements around a double - bond or ring structure. These molecules have the same molecular formula ($C_3H_8O$) but different structural arrangements of atoms and no double - bonds or ring structures for geometric isomerism.
Answer:
They are structural isomers.
