Solution

Solution Steps

Step 1: Understanding Molecular Orbital (MO) Diagrams

Molecular Orbital (MO) diagrams are used to describe the bonding in molecules by combining atomic orbitals to form molecular orbitals. Each molecule has a specific MO diagram based on its electron configuration and the number of valence electrons.

Step 2: Identifying the MO Diagram for $ \mathrm{N}_2 $

The nitrogen molecule ($ \mathrm{N}_2 $) has 10 valence electrons (5 from each nitrogen atom). The MO diagram for $ \mathrm{N}_2 $ typically shows the following order of orbitals:

$ \sigma_{2s} $, $ \sigma_{2s}^* $, $ \pi_{2p_x} = \pi_{2p_y} $, $ \sigma_{2p_z} $, $ \pi_{2p_x}^* = \pi_{2p_y}^* $, $ \sigma_{2p_z}^* $.

Step 3: Identifying the MO Diagram for $ \mathrm{O}_2 $

The oxygen molecule ($ \mathrm{O}_2 $) has 12 valence electrons (6 from each oxygen atom). The MO diagram for $ \mathrm{O}_2 $ typically shows the following order of orbitals:

$ \sigma_{2s} $, $ \sigma_{2s}^* $, $ \sigma_{2p_z} $, $ \pi_{2p_x} = \pi_{2p_y} $, $ \pi_{2p_x}^* = \pi_{2p_y}^* $, $ \sigma_{2p_z}^* $.

Step 4: Identifying the MO Diagram for $ \mathrm{F}_2 $

The fluorine molecule ($ \mathrm{F}_2 $) has 14 valence electrons (7 from each fluorine atom). The MO diagram for $ \mathrm{F}_2 $ typically shows the following order of orbitals:

$ \sigma_{2s} $, $ \sigma_{2s}^* $, $ \sigma_{2p_z} $, $ \pi_{2p_x} = \pi_{2p_y} $, $ \pi_{2p_x}^* = \pi_{2p_y}^* $, $ \sigma_{2p_z}^* $.

Final Answer

The MO diagram for $ \mathrm{N}_2 $ is diagram A.
The MO diagram for $ \mathrm{O}_2 $ is diagram B.
The MO diagram for $ \mathrm{F}_2 $ is diagram A.

\[ \boxed{ \begin{align_} \text{MO diagram for } \mathrm{N}_2 &: \text{diagram A} \\ \text{MO diagram for } \mathrm{O}_2 &: \text{diagram B} \\ \text{MO diagram for } \mathrm{F}_2 &: \text{diagram A} \end{align_} } \]
