Im confused on when you need to show the displayed formula of an isomer and it has bromine, carbon and hydrogen and it becomes dibromoethene? why does that happen? Thanks
If you watch from about 2.15 then it's a better explanation but basically it's for situations when there's more that one possibility for where the double bond could go. We number based on which carbon the double bond starts on, so that we can tell the difference
@@QianHueyWong-lz1sj because there’s no options for where to put the double bond. If you put it on the other side it’s still exactly the same molecule. We use the numbers when we have options to differentiate them

Cheers for this - have my mock exam for Chemistry tomorrow...... These are really useful for me to revise for my GCSE
You're welcome :) Hope they go okay!
I think I did okay but I found some of the questions hard

I think you're talking about addition reactions maybe? This might help... th-cam.com/video/cxk2mO7hKqc/w-d-xo.html
I want the structural formula of an alkene with 6 carbons
❤❤❤❤
I don't get why you wrote 1 or 2 in the middle

@@ChemJungle but why doesn't propene has it like prop-1-ene
