Polarity of Covalent Bonds

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What determines the polarity of a covalent bond?

Back

The polarity of a covalent bond is determined by the difference in electronegativity between the two atoms involved in the bond.

Front

What is electronegativity?

Back

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

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 a partial positive charge on one atom and a partial negative charge on the other.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of covalent bond where the electrons are shared equally between the two atoms, resulting in no charge separation.

Front

How can you identify a polar covalent bond?

Back

You can identify a polar covalent bond by checking if the two atoms have a significant difference in electronegativity (generally greater than 0.4).

Front

What is the bond type of NF3?

Back

NF3 has polar covalent bonds due to the difference in electronegativity between nitrogen and fluorine.

Front

What is the bond type of H2?

Back

H2 has nonpolar covalent bonds because the two hydrogen atoms share electrons equally.

Front

What is the bond type of SO2?

Back

SO2 has polar covalent bonds due to the difference in electronegativity between sulfur and oxygen.

Front

What is the bond type of HCl?

Back

HCl has a polar covalent bond because chlorine is more electronegative than hydrogen.
