Lesson Worksheet: VSEPR Theory Chemistry • 10th Grade
In this worksheet, we will practice predicting molecular geometries from the numbers of lone and bonding electron pairs and explaining variations in bond angle.
Q1:
Why is the bond angle of water () less than the bond angle for methane ()?
- AThe atom in water is sp2 hybridized.
- BMethane contains more bonds, so the bonds are forced further apart.
- CThe repulsion between a lone pair and a bonding pair is greater than the repulsion between two bonding pairs. Oxygen in water has two lone pairs and two bonding pairs, while the carbon in methane has four bonding pairs.
- DThe atom in water is surrounded by more electron pairs than the atom in methane.
- EThe bonding electron pairs in water repel each other more strongly than those in methane.
Q2:
Which of the following species has the smallest bond angle?
- A
- B
- C
- D
- E
Q3:
Which of the following species has the smallest bond angle?
- A
- B
- C
- D
- E
Q4:
In which of the following species is the angle between the bonds the smallest?
- A
- B
- C
- D
- E
