An alkane has a molecular mass of 72. Draw its possible chain isomers.

Dear Deva

First of all, we will derive the molecular formula.

Molecular formula of alkane is C_nH_2n+2

As molecular mass = 72,

12n + 2n + 2 = 72

n = 5

The alkane is C₅H₁₂. The possible chain isomers are

and

All the best.
