Answer to Problem 1.47AP
The orbital interaction energy diagram showing the energy levels of the atomic orbitals along with the energies of the given MOs is represented below.
Explanation of Solution
According to the rules for filling the electrons in the molecular orbital, first of all the lower energy molecular orbital is filled followed by the filling of increasing energy order of the molecular orbital.
Thus, the orbital interaction energy diagram showing the energy levels of the atomic orbitals along with the energies of the given MOs of oxygen atom is shown as,

Concept introduction:
The atoms which contain no unpaired electron in their orbital and have total spin equals to zero are known as diamagnetic atoms. The atoms which contain one or more unpaired electron in their orbital are known as paramagnetic atoms.

Answer to Problem 1.47AP
The liquid
Explanation of Solution
In oxygen molecule, two unpaired electrons are present in the anti-bonding molecular orbital. Thus, oxygen molecule is paramagnetic in nature due to which it gets attracted towards the magnetic field.
In comparison to liquid oxygen, the movement of the oxygen gas molecules is faster. Therefore, liquid oxygen molecules are not attracted by the magnetic field.
Hence, liquid

Concept introduction:
The Lewis structure shows the connectivity between atoms by identifying the lone pairs of electrons in a compound. Lewis structures are also called Lewis dot structures. The valence electrons around an atom are shown by dots. Bonds between atoms are shown by lines and the lone pair of electrons is shown by a pair of dots.
