An alkane has a molecular mass of 72 Give all the possible structural isomers along with their IUPAC names.

Explanation

To determine the structural isomers of an alkane with a molecular mass of 72 g/mol, we will follow these steps:

### Step 1: Determine the Molecular Formula
The general formula for alkanes is given by \( C_nH_{2n+2} \). Given that the molecular mass is 72 g/mol, we can set up the equation based on the molecular weights of carbon and hydrogen.

1. The atomic mass of carbon (C) is approximately 12 g/mol.
2. The atomic mass of hydrogen (H) is approximately 1 g/mol.
