Polarity and VSEPR review

Front

What are the two types of covalent bonds?

Back

Polar and nonpolar.

Front

What type of bond is formed when electrons are shared evenly between two atoms?

Back

Covalent nonpolar bond.

Front

What type of bond is formed when electrons are shared unevenly between two atoms?

Back

Covalent polar bond.

Front

What is a lone pair?

Back

A pair of non-bonding electrons.

Front

What is the characteristic of electrons in a polar covalent molecule?

Back

They are shared unevenly.

Front

What is the definition of a polar molecule?

Back

A molecule with a net dipole moment due to the presence of polar bonds.

Front

What is a nonpolar molecule?

Back

A molecule that has no net dipole moment, often due to symmetrical charge distribution.

Front

What is the VSEPR theory used for?

Back

To predict the geometry of molecular structures based on electron pair repulsion.

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

How does the presence of lone pairs affect molecular geometry?

Back

Lone pairs occupy more space and can alter bond angles.
