Question

Bef2 and BF3 both are stable yet each has incomplete octet. Why?​

Answer 1

Answer:

In BeF2 and BF3 , fluorine has lone pair of electrons, which are donated to the empty orbitals of beryllium and boron with the help of back bonding. Back bonding helps in stabilizing these compounds and hence, they exist even violating the octet rule.
