based on molecular theory, state whether or not the five following species exist, and if they do exist state whether they are paramagnetic, or diamagnetic. Justify answers in terms of the placement of electrons in molecular orbitals and the bond oder of each specie.

$$Be_2$$
$$O_{2}^{2+}$$
$$B_2$$

chmvijay · Answer

can u draw molecular orbitals for these molecules

chmvijay · Answer

Be2  doesnot exist 
B2 is paramagnetic 
O2+2 is diamagnetic 
He2+ is paramagnetic :)

freethinker · Answer

unfortunately I have to explain it in details

chmvijay · Answer

u dont noo molecular orbital how to put LOL

chmvijay · Answer

then wait LOL it takes long time to explain you everything :)

chmvijay · Answer

how can u know by intuition

freethinker · Answer

I have to do this as if I were giving the lecture…
