Question

The two isomers of butane have different

(1) formula masses (3) molecular formulas
(2) empirical formulas (4) structural formulas

Answer 1

(4) structural formula, isomers are differently structured forms of the same compound.

Answer 2

Answer: Option (4) is the correct answer.

Step-by-step explanation:

An isomer is defined as two or more compounds which represent same molecular formula but they have different structure, that is, differ in arrangement of atoms.

For example, butane and isobutane are isomers as they have same molecular formula but different arrangement of atoms.

Therefore, we can conclude that the two isomers of butane have different structural formulas.
