Chemistry - CHEMICAL BONDING Question with Solution | TestHub

A. Conduction in metals involves electron movement from the valence band (filled orbitals) to the conduction band (unfilled orbitals). This statement is CORRECT.

B. ${\pi }^{\ast }$ molecular orbitals are responsible for synergic bonding in complexes with $\pi$-acceptor ligands, not non-classical ligands. This statement is INCORRECT.

C. F₂ has a larger HOMO-LUMO gap than I₂, leading to lower color intensity. This statement is INCORRECT.

D. NO (11 valence electrons) and NO⁻ (12 valence electrons) are both paramagnetic. This statement is CORRECT.
