what best describes these three molecules? they are not isomers. they are structural isomers. they are geometric isomers. they are both structural and geometric isomers.

what best describes these three molecules? they are not isomers. they are structural isomers. they are geometric isomers. they 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.
