Answer 1

The isomers are the chemical compounds with the same molecular formula but different structures.Tetravalency and catenation is responsible for huge no. of carbon compounds.Moreover the huge no. of compounds is about 3 million!!

Answer 2

Compounds which have same molecular formula but occurs in 2 or more molecular structures are called isomers.
* properties
1) they have same molecular formula.
2) they differ in physical properties.
3) they have a different structural formula.
