1.	What is electron deficient and inert pair effect?
Answer» Nice explain yakshi<br>Hpe u will read and it will become easy for u to understand the concept<br>As we know that the meaning of inert is unreactive....similarly inert pair(of 2 electrons) effect can be defined as the tendency of pair of electrons in outermost or valence shell to remain unshared or unionised i.e remain unreactive<br>Actually these are two different terms......."ELECTRON DEFICIENT molecule or species is definded as a molecule or species that does not have enough valence electrons to complete their octet and that\'s why they are very unstable and have tendency to accept a pair of elecron to achieve stable electronic configuration and behave as lewis acid....." for example ...BeCl2 and BCl3
