Question

what is octet rule. write it's significance and limitations?​

Answer 1

Answer:

The octet rule proclaims that every atom will try to complete its octet in order to achieve its noble gas configuration.

it's limitations..

1. Incomplete octet.less than 8 electrons in centre atom ex Hcl
2. expanded octet. more than 8 electrons in centre atom. ex PCl5
3. Molecules having odd number of electrons. ex N02

_____________________

Octet Rule:

• The Octet Rule refers to a tendency of atoms to prefer to have eight electrons in the valence shell.When Atoms have Fewer than Eight electrons,they tend to react and form more stable compounds.

_____________________

Significance:

• The Octet Rule Successfully explains the formation of chemical bonds depending upon the nature of the element.It is used to determine stability in atoms.

____________________

Limitations:

• It can not be applied on non-metals after silicon in periodic table.
• These elements can expand their octet and have more than eight valence electrons around the central atom
• Molecules with an odd number of electrons cannot satisfy this rule
