Polarity and VSEPR review

Front

What type of molecule is chloroform (CHCl3)?

Back

Polar molecule.

Front

According to VSEPR theory, what do molecules adjust their shapes to keep as far away as possible?

Back

Pairs of valence electrons.

Front

What type of bond exists between two chlorine atoms in a Cl2 molecule?

Back

Covalent nonpolar bond.

Front

What type of bonds are present in the NH3 molecule?

Back

Covalent polar bonds.

Front

Why is CH4 considered a nonpolar molecule?

Back

It is symmetrical.

Front

Define polarity in molecules.

Back

Polarity refers to the distribution of electrical charge over the atoms in a molecule.

Front

What is VSEPR theory used for?

Back

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

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have a net dipole moment due to unequal sharing of electrons, while nonpolar molecules have no net dipole moment.

Front

Give an example of a polar molecule.

Back

Water (H2O) is a polar molecule.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.
