Textbook Question
Chapter 7.1, Problem 2PPB
The bond angle in NH3 is significantly smaller than the ideal bond angle of 109.5° because of the lone pair on the central atom. Explain why the bond angle in SO2 is very close to 120° despite there being a lone pair on the central atom.

The actual bond angle in NO₂ is 134.3°, and in NO₂⁻ it is 115.4°, although the ideal bond angle is 120° in both. Explain.
Answer the questions in the table below about the shape of the xenon tetrafluoride (XeF4) molecule.
How many electron groups are around the central xenon atom?
Note: one "electron group" means one lone pair, one single bond,
one double bond, or one triple bond.
