Explain the tetrahedral structure of chlorine oxide with a bond angle of more than
109º 28'.
the electronegativity of Cl is 3.16, and that of O is 3.44.
Cl2O has oxygen at the center (with chlorine having its typical valency as a halogen), and has 7+7+6=20 total valence electrons to distribute. The major resonance structure is:
Since oxygen is more electronegative, the negative electron density is mostly concentrated onto oxygen, which is closer to each bonding-electron pair (the electron density is closer together when you look near oxygen).
Therefore, oxygen's share of electron density repels the bonding-electron pairs more easily in each Cl−O bond than if the electronegativity difference was smaller.
This competes with the lone-pair repulsion, which would have contracted the bond angle...
Overall, the competing effects stack to increase the bond angle to a bit more than the expected 109.5∘, because...
Its actual bond angle is about 110.88∘.
- ClO2 has 7+6+6=19 total valence electrons to distribute (yes, it's paramagnetic). The major resonance structure is:
With two double bonds, the bonding-electron
