Interpretation:
The molecular property of oxygen that is explained by its molecular orbital diagram but not by Lewis structure has to be given.
(b)

Explanation of Solution
The molecular property of oxygen that is explained by its molecular orbital diagram is magnetic property.
The Lewis structure of oxygen is,
From the Lewis structure, it can be seen that all electrons are paired, and it is diamagnetic in nature. However, the molecular orbital diagram of oxygen (figure 1) shows the presence of two unpaired electrons and therefore, oxygen is paramagnetic.

Interpretation:
The nature of highest occupied molecular orbital in oxygen has to be given.

- Draw the mechanism for the following reaction: CH3 CH3 Et-OH Et Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron-flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. H± EXP.
