at 4:30 isn't dxy supposed to be higher in energy than dxz and dyz?

So we spent 29 lectures and still no even one example of inorganic synthesis? So u spent god know how long on studying some orbitals and energies but when they ask me in the labolatory how to plan total syntesis of potassium permanganate or some complexes i wont know? Nice chemistry u got there...

[sidewaysfcs]

another example would be Ni(Co)4, is Nickel d8 or d10? because it's d8 s2 in the free state, but it's d10 in the complex, since the two s electrons are relocated to the square-planar-split d orbitals

#6:32 Wrong information makes students

[clappingik]

It realy help me! Thank you for your upload

By definition, that's not metal's oxidation state, but it's oxidation number.

[kamataprasadyadav]

how can predict type of distortion i.e if d^4 high spin system

[alimajid]

fuck I wish I had seen this before the damn test

[sidewaysfcs]

the question of course is, how do we count the electrons for a ...let's say hypothetical Cu(CO)6 complex? and also, what is the d electron count of this copper?

the way i see it, here we should probably say the d and s count...because it's a d10 s1 if we consider the Cu(0) alone, but in the complex that additional s electron doesn't occupy an s orbital, it goes in t2g antibonding, since the CO is a pi acceptor ligand

and the total electron count in this complex would be 23 electrons

now, i suspect this is a highly unstable compound, but i'm curious if my rationale is correct

that "challenged" joke was really bad...

If he was being graded for public speaking, he would get an F.

[mmcquade]

What the hell... "...for those of you that are challenged..." this guy needs an attitude check.
