VSEPR and Covalent Compounds and Polyatomic

When two atoms share electrons, a chemical bond is formed.  This type of bond is called:

• covalent bond
• ionic bond
• crystal bond
• polyatomic bond

What is a double bond?

• a bond between two atoms
• one pair of electrons shared between two atoms
• two pairs of electrons shared between two atoms
• James Bond's brother

A covalent bond in which electrons are shared unequally is:

• polar
• a double bond
• ionic
• polyatomic

Which of the following is a characteristic property of molecular compounds?

• low melting points
• high melting points
• high boiling points
• high electric conductivity

Water is polar and oil is nonpolar.  What happens when the two liquids are poured into the same container?

• both liquids become nonpolar
• a gas is produced
• the liquids mix well
• the liquids do not mix well

Fluorine (F₂) is a(n)  _________________                  molecule because the valence electrons are shared equally between the two fluorine atoms.

• polar
• nonpolar
• ionic
• crystal

Because the electrons in a molecule of hydrogen fluoride (HF) are more strongly pulled toward the fluorine atom, the molecule is:

• polar
• nonpolar
• ionic
• charged

Carbon dioxide

• C₂O₂
• C₂0
• CO
• CO₂
