BeFg molecule In the gas phase, Be Fg forms lineas monomeric moleculds. The diagram of Befo is to the similar structure of co. molecule. The only difference is that there is a large energy separation between the be and & orbitals than the c and o orbitals.

In the gas phase , BeF2 forms linear monomeric molecule. The diagram of BeF2 is similar to the structure of CO2 molecule. The only difference is that there is a large energy separation between the Be and F orbitals than the C and O orbitals. The molecular energy level diagram is as shown below:
