Molecular orbital diagrams S-P mixing

------------------is the visual representation of the relative energy levels of molecular orbitals.

(a)  

Bonding molecular orbitals possess ---------------electron density .

• Low

• moderate

• Higher

Every electron in the anti bonding molecular orbital makes its contribution to the ---------- of two combining atoms.

• Repulsion

• Attraction

• Stability

• Same sign

Bonding molecular orbitals are formed when the lobes of combining orbitals with

• Opposite sign

• Same sign

• No need of sign

Anti bonding MO impart --------to the molecule .

• Instability

• Repulsion

• Lower energy

• 1&2

Moving from left to right 2p electrons are ----------- but 2s electrons remains constant .

(a)  

The Zeeman effect increases the energy gap between energy levels --------------

σ 1s﹤ σ*1s﹤σ2s﹤σ*2s﹤[π2px=π2py]﹤σ2pz﹤[π*2px=π*2py]﹤ σ*2pz

• Applicable From H2 to N2

• Applicable From O2 to Ne2

The distribution of electron density in the bonding and antibonding molecular orbitals formed follows ------------ rules

(a)  

From B2 to N2 the gap between S and P is Less. Hence------------ phenomenon is possible.
