Question

Give the shapes of bonding and antibonding MOs formed by combination of:
(i) two s-orbitals
(ii) two p-orbitals (side to side)

Answer 1

a) two s-orbitals – It is formed when a pair of electrons is shared among two s-orbitals thus by making a sigma bond orbital between them.

b) two p-orbitals (side by side) – it is an orbital formed when a pair of electrons is shared between two p-orbitals thus by making a pi-bond orbital.

 Also, the s-s orbital and p-p orbital overlap is given in the below figure
