Question

Despite some fundamental assumptions that are not verified by experiment, VSEPR theory can be used quite successfully to predict molecular shape. First, suggest how conversion of NO₂, which is a major component of air pollution, to either the respective cation (NO₂⁺) or anion (NO₂^-) will impact molecular shape. Second, think about one molecular property that would be impacted by such redox chemistry.

Answer 1

Answer: Compound Shape

NO2 Bent with bond angle 134.30

NO2 + Linear with bond angle 1800

NO2 - Bent with bond angle 1150

THe value of bond angle changes with the redox process.
