Which of the following molecules has a tetrahedral shape?
CF₄
CH2O
SO₃
H2O2
How do lone pairs of electrons affect the bond angles in a molecule?
Lone pairs have no effect on bond angles because they do not participate in bonding.
Lone pairs affect the length of the bond not the bond angle.
Lone pairs increase bond angles because bonded electrons are attracted towards the lone pair which cause the bonds within a molecule to spread apart.
Lone pairs decrease bond angles because they occupy more space than bonded electrons which squeezes the bonds within the molecule closer together.
Which of the following elements is most likely to be the central atom when drawing Lewis structures?
Bromine (Br)
Carbon (C)
Potassium (K)
Hydrogen (H)

What are the two key factors that affect the polarity of a molecule?
