What is inert pair effect ? |
| Answer» Solution :In case of elements of 4th, 5th and 6th period of p-block elements which COME after d-block elements, the electrons present in the INTERVENING d-or-and-f-orbitals do not shield the s-electrons of the valence shell effectively. As a RESULT, `ns^(2)`-electrons reamain more tightly held by the nucleus and HENCE do not participate in bonding. This is called inert PAIR effect. | |
