08 Covalent Bonding

Front

What is a covalent bond?

Back

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

Front

What is the difference between a single, double, and triple covalent bond?

Back

A single covalent bond involves one pair of shared electrons, a double bond involves two pairs, and a triple bond involves three pairs.

Front

What is the molecular formula for Dinitrogen trioxide?

Back

N2O3.

Front

What is the correct name for H2SO3?

Back

Sulfurous acid.

Front

What happens to the melting point of a substance with multiple covalent bonds?

Back

The melting point is generally higher because multiple covalent bonds must be broken to melt the substance.

Front

When naming oxyacids, what suffix is used for acids derived from '-ite' ions?

Back

'-ous'.

Front

When naming oxyacids, what suffix is used for acids derived from '-ate' ions?

Back

'-ic'.

Front

What is the significance of electronegativity in covalent bonding?

Back

Electronegativity determines how strongly an atom attracts shared electrons, influencing bond polarity.

Front

What is a polar covalent bond?

Back

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

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of bond where electrons are shared equally between atoms.
