Correct answer: B. ( &#963; 1 s ) &#60; ( &#963; * 1 s ) &#60; &#160; ( &#963; 2 s ) &#60; &#160; ( &#963; 2 s * ) &#60; ( &#960;

The molecular orbitals filled with electrons according Afbaue, Pauli's exclusion and Hund's rules. ( &#963; 1 s ) &#60; ( &#963; * 1 s ) &#60; &#160; ( &#963; 2 s ) &#60; &#160; ( &#963; 2 s * ) &#60; ( &#960; 2 p x ) = ( &#960; 2 p y ) &#60; &#963; 2 p z &#60; ( &#960; * 2 p x ) = ( &#960; * 2 p y ) &#60; ( &#963; * 2 p z ) The important characteristic feature of this order is that the energy of &#963; 2 pz molecular orbital is higher than that of &#960; 2 px &#160; and &#160; &#960; 2 py molecular orbital
