Question

Isomers have identical formulas and different

Answer 1

Answer:  Different Molecular Structures

Explanation: Isomers are the substances which have same molecular formula but different structures.

These compounds also have different physical and chemical properties.

For eg - CH3CH2OH and CH3OCH3 these both are isomers . They have different identical formula and different structure.

CH3CH2OH is ethyl alcohol and CH3OCH3 is dimethyl ether which is least polar and the former one is highly polar thus used as polar protic solvents in the nucleophillic substitution reaction.

This can be easily distinguished with the structures provided.

Answer 2

Molecular structure. Isomers have the same formula, so there is the same elements in both. But they have a different molecular structure and when drawn they look different
