What is inert pair effect?

Asked by Topperlearning User | 12th Aug, 2014, 10:50: AM

Expert Answer:

  • The reluctance of s-electron pair, of heavier elements, to take part in bond formation is known as inert pair effect.
  • This is due to poor shielding effect of intervening d and f orbitals, the increased effective nuclear charge holds ns electrons tightly and thereby, restricting their participation in bonding.
  • As a result of this, only p-orbital electron may be involved in bonding.
