Transition Metals - Complex Shapes and Isomers｜AQA A Level Chemistry

This video is intended to be an ultimate guide and revision on EVERY transition metal complex shape, bond angle and isomer you need to know for the 3.2.5.3 Shapes of complex ions section of the 3.2.5 Transition metals topic for the AQA A-Level chemistry specification. The aim of this video is to help all of you revise and prepare for your paper 1 and 3 exams.

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!

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!!

[ihannxh]

watching through all of your videos + doing exam qs as my last min rev 😩 it's helping so much thank you 💗💗

[Tatatata-hrsy]

Love the layout of these videos makes me want to be productive 😂

[yrboiqj]

can you make a whole paper predicted video going through the most likely topics and like key concepts ?? plz your videos are so helpful

[a]

Can you do more on types of isomers, electrodes, acids and bases equivalence points and testing for negative ions

[linhkhanh]

HI, at 10:52, I thought the cis isomer is the Z form?

[hantalgragas]

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.

This was extremely helpful thank you so so much ❤

[amii]

Hi can you please go through electrode potentials/electrochemistry. Btw I really love your vids I learn soooo much from them👍

[Comfort-vi]

Waw u are more excellent
Pls continue with for us

[nidaasghar]

hello,
you video are great can you please do more inorganics and practicals it will be very very helpful

[alexbesimming]

Would you be able to go over all the trends for the different groups and periods need for AQA?😭

[zxcbnm]

Hi Thanks
Is it possible if you could over hailide ions (H2So4 plz)

[sofiam]

hi could you please do a ‘topics to focus on’ for chem paper 2 too?

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

For aqa do we need to know about the colours of chromoium and cobalt?

[Ganothic]

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?

[Charisse_]

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
