Polarity

Front

What is polarity in chemistry?

Back

Polarity refers to the distribution of electrical charge over the atoms joined by the bond. It determines how molecules interact with each other.

Front

What type of bond involves the equal sharing of electrons?

Back

Nonpolar covalent bond.

Front

What type of bond involves the unequal sharing of electrons?

Back

Polar covalent bond.

Front

What is a polar molecule?

Back

A molecule that has a net dipole moment due to the presence of polar bonds, resulting in a positive and negative end.

Front

What is a nonpolar molecule?

Back

A molecule that does not have distinct positive and negative ends, often due to symmetrical charge distribution.

Front

In a polar covalent bond, which atom attracts the shared electrons more strongly?

Back

The atom with higher electronegativity.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons.

Front

Can nonpolar molecules have polar covalent bonds?

Back

Yes, nonpolar molecules can contain polar covalent bonds if the overall molecular symmetry cancels out the dipoles.

Front

What happens to the electrons in an ionic bond?

Back

Electrons are transferred from one atom to another, resulting in the formation of charged ions.

Front

What is the difference between polar and nonpolar solvents?

Back

Polar solvents can dissolve polar substances due to their ability to interact with dipoles, while nonpolar solvents dissolve nonpolar substances.
