Question

Isomer
What isomer is this

Answer 1

Answer:

Isomerism, the existence of molecules that have the same numbers of the same kinds of atoms (and hence the same formula) but differ in chemical and physical properties. Such structures also would be analogous to isomers.

Answer 2

Answer:

The  organic compound having the same molecular formula but different structures are called isomers

for example:

1. n-pentane, iso-pentane, Neo-pentane
2. n hexane, iso hexane , neo hexane

isomers is possible only with hydrocarbons having 4 or more carbon atoms because only then we can have 2 or more different arrangements of carbon atoms no isomers is possible in hydrocarbons containing 1 ,2 or 3 carbon atoms per molecule
