Question

im molecular orbital theory while arranging in increasing order of energy why is (π2p _x = π2p _y ?

Answer 1

Energy of an orbital is calculated by the formula (n+l)

For both,

2p_x and 2p_y

n=2 and l= 2

So for both of the orbitals (n+l)= 2+2 =4.

Hence both are of the same energy i.e. 2p_x =2p_y
