I know cause i just did it
The isomers butane and methyl propane differ in their structural formulas. Hence, option 2 is correct.
Structural formulas identify the location of chemical bonds between the atoms of a molecule.
Isomers are compounds with different physical and chemical properties but the same molecular formula.
In organic chemistry, there are many cases of isomerism.
For example, the formula [tex]C_4H_10[/tex] represents both butane and methylpropane.
Hence, option 2 is correct.
