Question

Assuming that during the formation of X 2 + ​ from X 2 ​ the bond length increase while during the formation of M 2 − 2 ​ from M 2 ​ bond length decrease, where ( 6 < atomic number of x < 10 ) and ( 5 < atomic number of M < 10 ) From given information which of the following statement is incorrect?

TestHub · Accepted Answer

Identify X₂: An increase in bond length during $X_{2} \to X_{2}^{+}$ means an electron is removed from a bonding molecular orbital (BMO), identifying X₂ as N₂ ( $Z = 7$ ).

Identify M₂: A decrease in bond length during $M_{2} \to M_{2}^{2 -}$ means electrons are added to a BMO, identifying M₂ as C₂ ( $Z = 6$ ).

Analyze M₂ orbitals: The last electrons in C₂ occupy the $π_{2 p_{x}}$ and $π_{2 p_{y}}$ bonding molecular orbitals.

Determine nodal planes: A $π_{2 p}$ bonding molecular orbital contains only 1 nodal plane (the internuclear plane), making statement (D) false because it states there are 2.
