Why isn’t azete aromatic?
10 votes

The compound is anti-aromatic. While counting the number of π-electrons, you count the electrons which are delocalized over the ring. In this case the nitrogen lone pair is localised and does not ...

Why does small value of van der Waals gas constant "b" ensure easier liquefication?
4 votes

The virial equation of state reads: $$Z = 1 + \left(b - \frac{a}{RT}\right)\frac{1}{V_\mathrm{m}} + \left(\frac{b}{V_\mathrm{m}}\right)^2 \cdots$$ Going by this equation, it seems like increasing ...

How can transition metals form so many bonds with ligands?
1 votes

Copper is in +2 oxidation state so it has configuration $\ce{[Ar] 3d^9}$. Since 4s, 4p and 4d orbitals are vacant, Cu will show $\ce{sp^3d^2}$ hybridisation and will accept these elctron pairs in its ...

How to calculate molality, molarity and mole fraction given density (g/mole)?
1 votes

First let me correct you, m/m means mass/mass % I think you assumed it to be mole/mole. Assume you have 100g of solution in which Cu is 17g and solvent is 83 gm. 17 gm copper means 0.268 moles of Cu. ...
