hope it helps

Answer 2

Octet rule states that atoms of elements has tendency to achieve eight electrons in their outermost cell.

But some elements stood as exception to this rule, marking it's limitation.

━━━━━━━━━━━━━━━━

• Hypovalent molecules:

In some compounds or in some molecules octet is not completed in outermost orbit of central atom.

Example: Halides and Hydrides of III-A group, BCl3 etc

━━━━━━━━━━━━━━━━

• Hypervalent molecules:

In some compounds or in some molecules the outermost orbit of central atom has more than eight electrons

Example: In PCl5, P contains 10 electrons

━━━━━━━━━━━━━━━━

• Odd electron molecules:

In some molecules the central atoms contains an unpaired electron.

Example: NO, NO2, ClO2 etc

━━━━━━━━━━━━━━━━

• Pseudo Inert Gas Configuration

Some cations contain 18 electrons in their outermost orbit.

Example : Ga+3, Cu+ etc
