Question #bcdd5

Answer 1

Here's one way to draw them.

Explanation:

There are many isomers with the molecular formula `"C"_7"H"_14`.

I'm guessing that you are interested in the stereoisomers.

Then, there are only two isomers.

One has the methyl group on `"C-2"` "up" (a wedge) and the other has the methyl group "down" (a dashed line).
