Question

find the number of isomers of an alkane with molecular weight 72​

Answer 1

Answer:

12 isomers for alkane with molecular weight 72

Answer 2

Answer:

First of all, we will derive the molecular formula.

Molecular formula of alkane is CnH2n+2

As molecular mass = 72,

12n + 2n + 2 = 72

n = 5

The alkane is C₅H₁₂.

Pentane (C₅H₁₂) has three structural isomers.
