IMPORTANT: I made a mistake when initially discussing the E-Z isomers in alkenes and when I say that cis is the same as E isomers and trans is the same as Z isomers, this is incorrect! The info regarding cis and trans isomers is still all correct, but the E and Z should be the opposite way round. Cis = Z, Trans = E, My bad guys!
@easymodeexams33 even at 8:00 you said the E and Z the wrong way
@@winniethepooh8766 yeah my bad, hopefully you understand which is which
Honestly such a lifesaver
This was a beautiful video. Second year at college rn, and finally have motivation to work hard. It's really late, and I'm kicking myself for not trying before. But better late than never.
Love the practice recall bit at the end, really helpful, and forces me to stay focus and not let my brain drift away.
How on earth do you only have 5k subs, this is literally one of best videos out there!!
Thanks for the beautiful comment Anna :) you've defo got enough time until exam season, good luck
watching through all of your videos + doing exam qs as my last min rev 😩 it's helping so much thank you 💗💗
no worries :) past exam qs is defo good last min revision, good luck!
can you make a whole paper predicted video going through the most likely topics and like key concepts ?? plz your videos are so helpful
Can you do more on types of isomers, electrodes, acids and bases equivalence points and testing for negative ions
Love the layout of these videos makes me want to be productive 😂
😂 thnx
Hi can you please go through electrode potentials/electrochemistry. Btw I really love your vids I learn soooo much from them👍
Thank you so much !!!
you're welcome :)
This was extremely helpful thank you so so much ❤
no worries :) good luck
I never understood isomerism in transition metals and always confused between cis and trans as I was used to using E-Z notation but this video was such a life safer, considering this actually came up in the exam today I am so thankful to you! Easy 3 marks.
I'm glad it helped you out :)
Thanks
Hi Thanks
Is it possible if you could over hailide ions (H2So4 plz)
hello,
you video are great can you please do more inorganics and practicals it will be very very helpful
I'm glad you find them helpful :) I will try to do more practical videos towards paper 3 if I have time
Waw u are more excellent
Pls continue with for us
Thank you :)
Would you be able to go over all the trends for the different groups and periods need for AQA?😭
I'm afraid I don't have the time sorry, working on a long electrode potentials video for tomorrow and it's taking ages haha
@@easymodeexams33 ooh that's nice! I always struggle with that 😭
hi could you please do a ‘topics to focus on’ for chem paper 2 too?
yeah sure, working on it :)
HI, at 10:52, I thought the cis isomer is the Z form?
yeah correct and trans is E.
@@joshuahoward2956 so is CIS z and TRANS e ?
yeah you're correct, my bad! I got Z and E the wrong way round. I've left a pinned comment so hopefully people can see that :)
@@sadmarcharicheese2041 yeah, I got E and Z the wrong way round 😅😅
How i remember it is 'Cis' sounds more like Z rather than E, if it works it works 😅
For aqa do we need to know about the colours of chromoium and cobalt?
No, I believe they were taken off the spec! :)
For drawing the bidente isomers is it imperative to draw the bond from the N (of NH2) to the C( of CH2) in ethane1,2diamine
What would the alternative be? (not being rude, just trying to understand what you had in mind)
Hi, how can you tell if a complex is going to be tetrahedral or square planar ? I know transition metal ions commonly form tetrahedral complexes with larger ligands like [CuCl4]2- but how could you tell that complex was tetrahedral instead of square planar because square planar can also have Cl ligands
only cis platin is the one u need to know for square planer the others are tetrahedral
How do you know when it's going to be tetrahedral and when it's going to be a square planar just looking at the molecular formula?
It depends how many bonding/lone pairs the central metal ion has.if it has 4 bonding pairs, and 2 lone pairs left over, then that will be square planar as the lone pairs will be positioned 180 degrees away from each other (one at the top and one at the bottom). So square planar is basically octahedral but instead of a ligand on the top and the bottom it’ll be lone pairs. Hope this helps
Is cis not Z and trans not E?
ur right
you're 100% right, cis is Z and trans is E, my bad! the cis and trans are still correctly explained in the video tho
@@easymodeexams33 no worries! Just wanted to make sure i wasn't going crazy. Thanks if for clearing this up, love ur content bro
@@sahib3035 haha I get u, defo not crazy. Thanks, happy to help :) It's genuinely helpful for me when people pick up on my errors because I am just free flowing these videos and edit myself so miss small mistakes haha
@@easymodeexams33 how would you know whether something is square planar or a tetrahedral when in transition metals never really get it
huh i thought cl- was bigger than h2o
correct my g
@@easymodeexams33 how come the cl joining doesnt change the shape of the octahedral complex
