Shape of Molecules & VSEPR
1. Discuss the shape of the following molecules using the VSEPR model: BeCl2, BCl3, SiCl4, AsF5, H2S & PH3
2. Although geometries of NH3 and H2O molecules are distorted tetrahedral, bond angle in water is less than that of ammonia. Discuss
3. Draw an example of each of the following :
- Tetrahedral
- Triagonal Bipyramidal
- Pentagonal Bipyramidal
- Linear
- See – Saw
- Angular / V – shape
4. Why Axial pairs are longer than Equatorial pair?
5. Which Structure is Correct and Why?
6. Why Lone pair – Lone pair repulsion is higher than Lone pair – Bond pair and Bond pair – Bond pair ?
7. What makes PCl5 is Highly reactive?
