Question

How would you draw the four possible stereoisomers of 3-bromo-4-fluorohexane?

Answer 1

I would draw their Fischer projections.

Explanation:

1. Start by drawing four Fischer projection templates, with `"C-1"` at the top.

2. Now add the `"F"` atoms at `"C-4"`, with two to the right and two to the left.

3. Next, add the `"Br"` atoms to `"C-3"`, alternating right-left-right-left.

4. Finally, add the missing `"H"` atoms to `"C-3"` and `"C-4"`.

And you have your four stereoisomers.
