Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Molecules like NO₂ (17 valence electrons), ClO₂ (19 valence electrons), and NO (11 valence electrons) are odd-electron species.

Because they possess an unpaired electron, they are inherently paramagnetic and fail to satisfy the octet rule for all atoms.

CO₂ contains 16 valence electrons, which pair up completely to form a stable linear structure (O=C=O). Therefore, CO₂ has no unpaired electrons (diamagnetic), and every atom fully satisfies the octet rule.
