Gen Chem Q

Hello. 🙂

I'm using Chad's videos now and I was wondering if anyone could explain the hybridization of

[Ni (NH3)6 ] 2+

There are 6 e- domains, making it an octahedral shape.
But how do you know what the hybridization would be?

AND

Why doesn't SO2 form 4 double bonds? ( lone pair + 4 bonds = 6)

Instead, it displays resonance structures with 3 bonds + lone pair.

Thanks 🙂
chem is my weakness.

hybridization is pretty simple. an atom with 6 electron domains around it is always going to be d2sp3. something with 5 will be dsp3, something with 4 will be sp3, something with 3 will be sp2, something with 2 will be sp.

for your second question, i believe those are all resonance structures of each other. you would be correct in writing O=S=O (with the lone pairs) as the Lewis structure. it's the better lewis structure.
