Question

The number of structural isomers having molecular formula c6h14 is

Answer 1

Answer:

Structural isomer of Hexane(C6h14) is FIVE(5).

Trick :

This trick can help you calculate the number of isomers of alkanes;

2ⁿ⁻⁴ +1  {where n is no. of carbon atom}

Example : Q. Find the no. of isomer of butane(c4H10):

solution: no. of carbon atoms(n) = 4

now put it into the trick , 2^(4-4)+1 = 2^0+1 = 1+1 +2

Therefore the number of isomer can be formed by butane is 2
