1) Find the odd-electron molecules from the following. $C_{2}H_{2}$, $SCl_{2}$, NO, $N_{2}$ , $NO_{2}$ as (I) , (ii) , (iii) , (iv) , (v) respectively A) i,iii,iv B) ii,iii C) i,iv D) iii, v Answer: Option DExplanation: NO and $NO_{2}$ species are having odd electrons and disobey the octet rule. Formal charges and the molecule's resonance structure are indicated.
