Chapter 10, Problem 119DIA

The VSEPR model is useful in predicting bond for many compounds. Consider the tabulated data for bond angles in related species and answer the questions.

Bond Angles in NO2 and Associated lons
Species	Bond Angles
${\text{NO}}_{\text{2}}$	$134°$
${\text{NO}}_{\text{2}}{}^{+}$	$180°$
${\text{NO}}_{\text{2}}{}^{-}$	$115°$

(a) Draw Lewis structure for all of the species in the table.

(b) Use the Lewis structure from part a) to explain the observed bond angles in ${\text{NO}}_{\text{2}}$ and its associated ions.
