From their IUPAC name we can clearly find that all molecules are alkane. And all have 7 Carbon. So number of Hydrogen = 2*(Number of carbon) + 2 = 16
All have same molecular formula of C7H16 but having different structure. So they are called Isomers.
Same molecular formula but different structure comes into the category of Stuctural Isomers. Structural Isomers are also known as Constitutional Isomers. Hence they all are Structural Isomers with each other.
If you find this solution helpful then please give a thumbsup ?. Thankyou.
