Write the significance and limitations of octet rule

Answered by admin @



Significance of octet
rule:
  
    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.
     The octet rule helps to figure out how
atoms will bond with one another.

 


limitations of octet
rule are:
 Some limitations of the
octet rule are: It cannot be applied to the nonmetals after silicon in the
periodic table. These elements can “expand their octet” and have more than
eight valence electrons around the central atom. Examples are PF₅ , SF₆ and H2SO4 . Helpful 1 Confusing 1 Molecules with an odd number of
electrons such as NO and NO₂ cannot satisfy the octet rule. At least one atom must have an odd number
of electrons. In some molecules the central atom cannot possibly have eight
valence electrons. For example, LiCl, BeCl₂ and BCl₃ do not obey the octet rule.
