Chemistry - CHEMICAL BONDING Question with Solution | TestHub

(A) The nitrogen atom is shown with a +2 formal charge, which is incorrect because nitrogen rarely exhibits such a high positive charge in stable compounds. Also, the bonding and electron arrangement violate the octet rule.

(B) The Lewis structure of nitrogen and oxygen is incorrectly drawn, with improper lone pairs and bonding that do not satisfy octet or formal charge rules.

(C) H–C≡N: is correctly drawn, showing hydrogen bonded to carbon which is triple bonded to nitrogen, with proper electron pairs and octet completion.

(D) The structure of N₃⁻ (azide ion) with formal charges –1, +1, –1 is correctly represented, satisfying octet and charge distribution.
