Question

Which of the following choices represent the resonance contributors of HCI. Note that "aq" was not included next to the molecule, and so, in this instance, we are considering molecules in the gas phase. Hint: consider electronegativity differences H: CI: I is the major resonance contributor; Il is a minor resonance contributor; Il is an insignificant resonance contributor. l is the major resonance contributor; lll is a minor resonance contributor, ll is an insignificant resonance contributor. IlIl is the major resonance contributor: II is a minor resonance contributor; is an insignificant resonance contributor. Il is the major resonance contributor; I is a minor resonance contributor; II is an insignificant resonance contributor. Il is the major resonance contributor; IIl is a minor resonance contributor; is an insignificant resonance contributor. Ill is the major resonance contributor; I is a minor resonance contributor; Il is an insignificant resonance contributor.

Answer 1

II is the major resonance Contributor, I is a minor resonance contributor III is an insignificant resonance Contributor Explanation: - Cl is more electro negative than H so H - Cl is a Polar molecule electrons shifts towards more electro negative Cl atom . So III is insignificant.
