Question

what is octet rule and write its limitations​

Answer 1

Hey Mate!

Explanation:

Octect Rule says that an element should have 8 Electrons in the Valence shell to be Stable.

Elements with less than 8 total electrons donot follow the Octect Rule..

Hope It helped you!!!!

RATE WELL!!!

Answer 2

Explanation:

Octet rule fails to explain the following:

(1) The stability of incomplete octet molecules, i.e., the molecules with the central atom containing less than eight electrons.

For example, $\sf{BeCl_2}, {BF_3}$.

(2) The stability of expanded octet molecules, i.e., the molecules with the central atom containing more than eight electrons.

For example, $\sf{PC_5}, {SF_6}$.

(3) Observed shape and geometry of the molecules.

(4) Difference in energies and reactivities of different molecules.
