Polarity Review

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.

What is a polar covalent bond?

Back

A polar covalent bond is a type of chemical bond where a pair of electrons is unequally shared between two atoms, leading to a partial positive charge on one end and a partial negative charge on the other.

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 greater the difference in electronegativity between two atoms, the more polar the bond will be.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of bond where two atoms share a pair of electrons equally, resulting in no charge separation.

Front

What is the electronegativity difference for a nonpolar bond?

Back

The electronegativity difference for a nonpolar bond is typically less than 0.4.

Front

What is the electronegativity difference for a polar covalent bond?

Back

The electronegativity difference for a polar covalent bond is typically between 0.4 and 1.7.

Front

What is the electronegativity difference for an ionic bond?

Back

The electronegativity difference for an ionic bond is typically greater than 1.7.

Front

What type of bond is formed between two metals?

Back

A metallic bond is formed between two metals, characterized by a 'sea of electrons' that are free to move.

What is the shape of a molecule with polar bonds but is nonpolar overall?

Back

A molecule like carbon dioxide (CO2) has polar bonds but is nonpolar overall due to its linear shape.
