Instead of drawing them all out, I usually just draw out the C’s. Then I imagine it by working onwards and out if that makes sense. For example, you have the c-c-c-c. Then, working inwards, there’s the possibility of 2 f’s on c1, c2, c3, then outwards, the possibility of 1 f on either outer carbon, and one f on either inner carbon. Then the final one is an f on c1 and c3. That’s the trick I usually use. I think you’ll find that with supposed 1 marker questions in chemistry, there’s actually a lot of working out that goes into it

That’s a good trick, thanks for the help
