Vedclass · Answer

(D) $Pauli's$ exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers,which implies that an orbital can hold a maximum of two electrons with opposite spins. $Hund's$ rule of maximum multiplicity states that electron pairing in degenerate orbitals (like $p$,$d$,$f$) does not take place until each orbital is singly occupied. In option $d$,the first orbital shows two electrons with the same spin (violating $Pauli's$ exclusion principle),and the second set of orbitals shows pairing before all orbitals are singly occupied (violating $Hund's$ rule).

In which of the following orbital diagrams are both Pauli's exclusion principle and Hund's rule violated?
