Why is it wrong to use the concept of hybridization for transition metal complexes?
9 votes

For the most part, coordination bonds involve d electrons from the transition metal interacting with some other electrons on a separate molecule. Hybrid orbitals are constructed from a single atom's ...

Ionic factor of glucose?
Accepted answer
6 votes

A more appropriate name for the ionic factor is the van't Hoff factor of colligative properties. In the simplest terms, it is the number of particles created after being dissolved in the solution. ...

How to find if the unpaired electron is placed in hybrid orbital or pure orbital in odd electron species?
5 votes

When discussing hybrid orbitals, they are justified by the experimentally observed or calculated/simulated molecular geometry. For instance, the $\ce{^.C(CH3)3}$ radical was found to be planar by ab ...

Is graphene a combustible material?
Accepted answer
4 votes

Graphene combusts at 620 K. See http://pubs.acs.org/doi/abs/10.1021/jp410044v. It is postulated that it burns at this temperature "because of a large interlayer spacing of graphene sheets (i.e., 5.1 ...

Why is that in zwitterions amino acids or compunds with amine and acid group are mentioned but not compounds with alchol and acid group?
2 votes

That is precisely the reason why. Zwitterions are defined as molecules that contain both a positive and a negative charge within the molecule. Alcohol groups won't deprotonate at neutral pH = 7. The ...

Why in solution glucose not convert into galactose or mannose?
Accepted answer

Yes, carbon-carbon bond rotation can happen in the open chain form of these carbohydrates. But you are confusing rotation with stereochemical configuration. This can only be altered by breaking bonds. ...

E-Z notation should be used here. But to answer your question, the longer chain off the double bond takes the priority. In this case, it is the ethyl group. So product 1 is trans while product 3 is ...

What is the systematic name of ammonium bisoxalato cuprate (II)?
2 votes

Did you mean to ask "what is the chemical formula of ammonium bisoxalatocuprate(II)", yes? If so, the compound is a salt and should be chargeless. $$\ce{(NH4)2[Cu(C2O4)]}$$ This is because oxalate is -...

Is hybridization used in ab initio valence bond calculation?
-1 votes

I can answer your first question definitively from my experience in quantum chemistry. Yes, hybrid orbital basis sets are still used, albeit minimally. Typically, these basis sets are used in QM/MM in ...
