Unit 3 - Drawing Compounds and Molecules

Front

What type of bond is characterized by unequal sharing of electrons?

Back

Polar covalent bond.

Front

What is the molecular shape of SiCl4?

Back

Tetrahedral.

Front

How can you determine if a molecule is polar?

Back

By analyzing the symmetry of the molecule and the electronegativity differences between atoms.

Front

Is CCl4 polar or nonpolar?

Back

Nonpolar.

Front

What is the correct Lewis dot structure for the molecule fluorine (F2)?

Back

B.

Front

What is a nonpolar covalent bond?

Back

A bond where electrons are shared equally between two atoms.

Front

What is the significance of electronegativity in determining bond type?

Back

Electronegativity differences between atoms determine whether a bond is ionic, polar covalent, or nonpolar covalent.

Front

What is the VSEPR theory used for?

Back

To predict the geometry of molecules based on repulsion between electron pairs.

Front

What is the shape of a molecule with four bonding pairs and no lone pairs?

Back

Tetrahedral.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have a net dipole moment due to uneven distribution of electrons, while nonpolar molecules do not.
