Interpretation Introduction

(a)

Interpretation:

The ideal bond angles in NO2- need to be determined.

Concept introduction:

  • In molecules with more than 2 atoms, the angle formed between 2 bonds is called as the bond angle.
  • The ideal geometry adopted by various molecules can be predicted based on the valence shell electron pair repulsion (VSEPR) theory. As per the VSEPR model, an orbital arrangement which minimizes valence electron repulsion leads to a stable geometry.
  • The geometry of a given can be predicted based on the general formula: AXn Em where A = central atom, X = surrounding atoms, E = lone pairs on the central atom

Interpretation Introduction

(b)

Zeolites: environmental applications.
" is The structure of the bicarbonate (hydrogen carbonate) ion, HCO3-, HCO3 best described as a hybrid of several contributing resonance forms, two of which are shown here. HO :0: :Ö: HO + Bicarbonate is crucial for the control of body pH (for example, blood pH: 7.4). A more self-indulgent use is in baking soda, where it serves as a source of CO2 CO₂ 2 gas, which gives bread and pastry their fluffy constituency. (i) Draw at least one additional resonance form. = (ii) Using curved "electron-pushing" arrows, show how these Lewis structures may be interconverted by movement of electron pairs. (iii) Determine which form or forms will be the major contributor(s) to the real structure of bicarbonate, explaining your answer on the basis of the criteria in Section 1-5.
