Bond polarity and molecular shape (VSEPR) — Homework
Show the electronegativity subtraction (or the electron-group count) for every problem.
- 1.Nitrogen is about 3.0 and hydrogen is about 2.1. Classify the N-H bond.
- 2.Potassium is about 0.8 and fluorine is about 4.0. Classify the K-F bond.
- 3.A central atom has 3 bonding pairs and 0 lone pairs. What shape does VSEPR predict?
- 4.A central atom has 3 bonding pairs and 1 lone pair (4 total electron groups). Is the molecular shape still trigonal planar? Explain.
- 5.Explain why the O-H bond in water is polar, but the overall water molecule's bent shape matters for its properties beyond just the bond itself.
