Hello, this is really helpful. Could you please do paper 2 variant 2. I really need help with the last question specifically

[@OAT_AN]

Thanks, I'll try to do it soon

[@EricYu-p5t]

thanks for you video!!! can you explain a bit more why are there 8 isomers? cuz one chiral centre gives 2 optical isomers and cis-trans creates 2 as well, i thought it is only 6 in total

[@hazranhazam3967]

Yeah i thought the same 2

[@4chels]

because each cis-trans has two types, and if you have 4 of optical isomers u will have 2x4=8 in total because of the different combinations as the two types can occur at the same time
(for each optical isomer you can have cis or trans)
