The molecule in which an atom is associated with more than 8 electrons is known as hypervalent molecule and less than 8 electrons is known as hypovalent molecule. All hypervalent molecules must have `ppi-dpi` bonding but the molecules having back bonding back boding need not to have always `ppi-dpi` bondin.
Q. Which of the following is having complete octet:

A

`BeCl_(2)` (dimer)

B

`BeH_(2)` (dimer)

C

`BeH_(2) ` (s)

D

`BeCl_(2)` (s)
