Question

How to find number of isomers in organic compound.

Answer 1

to find number of isomers in organic compound, find the atomic mass and divide it by the total number of molecules.

Answer 2

The number of isomers could not be found using any formula because there’s no formula to calculate the number of isomers in organic compound. A certain number of carbons can branch out even though they are unstable and do not really exist. Consider the example C4H10.

Here it represents both butane and also 2-methylpropane.

The first ten are:

Number of carbons   ->  Number of structural isomers

0 -> 1

1 -> 1

2 -> 1

3 -> 1

4 -> 2

5 -> 3

6 -> 5

7 -> 9

8 -> 18

9 -> 35

10 -> 75
