For a hydrocarbon with the molecular formula , which is an alkane, we can determine the possible chain isomers by drawing all unique structures with the same molecular formula.
The chain isomers for are as follows:
Straight Chain (Heptane):
Branched Chains (Various Isomers):
Each of these structures represents a distinct arrangement of carbon atoms, satisfying the molecular formula .
Conclusion:
There are a total of 9 different chain isomers for .
The remainder when is divided by 7 is equal to:
