What is the inert pair effect ? |
|
Answer» Solution :In the elements of 4th, 5TH, and 6th periodof the p-block elements which COME after d-block elements, the electrons present in the interveningd- and f-orbitals do not shield the s-electron of the valence shell effecitively. As a result, `ns^(2)`-electrons remains more tightly held by the nucleusand hence do not participate in bonding. This is called INERT pair effect. |
