Polarity Practice

Front

What is polarity in chemistry?

Back

Polarity refers to the distribution of electrical charge over the atoms in a molecule, leading to a molecule having a positive end and a negative end.

Front

What is a polar molecule?

Back

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

Front

What is a non-polar molecule?

Back

A non-polar molecule is one that does not have a net dipole moment, meaning the electrical charges are evenly distributed.

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

How does electronegativity affect bond polarity?

Back

The difference in electronegativity between two atoms determines the polarity of the bond; a larger difference leads to a more polar bond.

Front

What type of bond is formed between atoms with a large difference in electronegativity?

Back

An ionic bond is formed between atoms with a large difference in electronegativity.

Front

What type of bond is formed between atoms with a small difference in electronegativity?

Back

A covalent bond is formed between atoms with a small difference in electronegativity.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where the electrons are shared unequally between the two atoms, resulting in partial charges.

Front

What is an example of a polar molecule?

Back

Water (H2O) is an example of a polar molecule due to its bent shape and the difference in electronegativity between hydrogen and oxygen.

Front

What is an example of a non-polar molecule?

Back

Carbon tetrachloride (CCl4) is an example of a non-polar molecule because its symmetrical shape cancels out any dipole moments.
