Can you guys please help me how to count how many isomers in a substance. I see this type of question usually appears in MC section but not sure how to do? Is there any formula? Thanks.

I usually just draw them out and see how many I make, but iirc I did research on this and found a chart with the number of isomers to carbon chain length plot
