Question

Draw the Lewis structure for chlorate and nitrite and indicate which is the best structure upon examining resonance structures.

Answer 1

Hi,

Hope you are doing well.

__________________________________________________________________________

RESULT:

1. Number of resonance structures in chlorate ion (ClO₃^-) is 3.
2. Number of resonance structures in nitrite ion (NO₂^-) is 2.
3. Therefore, No.of resonance structures in chlorate ion is greater than no.of resonance structures in nitrite ion. Hence, chlorate ion is more stable. Therefore, best structure is that of chlorate ion.

EXPLANATION:

PART 1: Chlorate (C10g) Lewis structure: Resonance structures : No. of Resonance structures = 3 PART 2: Nitrite (NO2) he wis structure: Pro:Ñ::ö: Resonance structures : - Ñ < No.of resonance structures - 2 2
