Inert Pair Effect:-
1) Inertness of ns^2 electron to participate in Chemical Bonding..
2) On moving from 5th to 6th Period In P-BLOCK there is an increment of 32 atomic number but due to poor shielding effect of D and F electrons nucleus exert a strong attraction and therefore ns^2 electron is tightly HELD TOWARDS NUCLEUS....
3) ns^2 electron will not be able to participate in Chemical Bonding. THIS IS CALLED INERT PAIR EFFECT..
e.g:- Tl, pb, Ni, etc..

Bcoz Of the reason that Sn is moving from 4th period to 5th period there will not be Inert Pair Effect..
Thank you....

ELEMENTS IN THE P-BLOCK HAVE GENERAL CONFIGURATION
ns2 np2
Here the electrons of the s orbital (ns2) tend not to participate in chemical reactions. Thus the 2 electrons of p orbital are only available for reactions. This makes +2 oxidation state more stable than +4 in the lower elements of the 14th group. This effect is called inert pair effect.
Thus SnCl4 (which has oxidation state +4) is less stable than SnCl2 (which has oxi. state +2).....
Hope u understood !!!!
