Covalent Compounds and Bond Polarity Flashcard

Front

What is a covalent bond?

Back

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

Front

What is the difference between polar and nonpolar bonds?

Back

Polar bonds have an unequal sharing of electrons due to a difference in electronegativity between the bonded atoms, while nonpolar bonds have an equal sharing of electrons.

Front

Identify a characteristic of nonpolar molecules.

Back

Nonpolar molecules typically have symmetrical shapes and do not have a significant difference in electronegativity between the atoms.

Front

What is electronegativity?

Back

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

Front

How do you determine if a bond is polar or nonpolar?

Back

To determine if a bond is polar or nonpolar, compare the electronegativities of the two atoms involved in the bond.

What is the molecular formula for carbon tetrachloride?

Back

The molecular formula for carbon tetrachloride is CCl₄.

Front

What is the molecular formula for chlorine dioxide?

Back

The molecular formula for chlorine dioxide is ClO₂.

Front

What is the molecular formula for dinitrogen monoxide?

Back

The molecular formula for dinitrogen monoxide is N₂O.

Front

Give an example of a nonpolar bond.

Back

An example of a nonpolar bond is the H-H bond.
