Question
Discuss the formation of compounds in which octet rule is violated.
Solution
There are some exceptions to the octet rule:
(i) Formation of compounds like BeCl2, BF3 AlCl3 etc. In each of these molecules, the central atom (Be, B or Al) has less than 8 electrons i.e. these are electron deficient compounds.
(B and Al have 6 electrons around them.)
(ii) Formation of compounds like PCl3, SF6, IF7 etc. In each of these molecules, the central atom has more than 8 electrons.
The octet rule is violated in these molecules.
