10 Questions
In the VSEPR theory, what happens to bond angles when there are lone pairs present?
Bond angles decrease
What is the shape of a molecule with 4 electron pairs and only 3 bonds?
Trigonal pyramid
How does the VSEPR theory explain the shapes of molecules with lone pairs?
The lone pairs repel bonding pairs, affecting bond angles
What is the shape of a molecule with 5 electron pairs?
Square pyramid
Which pair experiences the most repulsion in molecules with multiple lone pairs?
Lone pair + lone pair
What is the effect of having more than one lone pair in a molecule?
Bond angles decrease
How does the presence of lone pairs impact the final shape of a molecule?
It affects the symmetry and overall shape of the molecule
What is the impact of lone pairs on bond angles?
They decrease bond angles due to increased repulsion
Which molecule shape involves a 'trigonal pyramid' configuration?
ClF4+
How does lone pair positioning affect molecular geometry?
It significantly alters the molecular geometry
This quiz challenges you to predict which molecule between Cl2 and I2 will have the highest boiling point, and to explain the difference. It also asks why pentane has a higher boiling point than 2,2-dimethylpropane despite having the same formula. Test your understanding of intermolecular forces and boiling points.
