Covalent Nomenclature and Lewis Stuctures

Front

What is a lone pair?

Back

A pair of non-bonding electrons.

Front

What is the chemical formula for disulfur trioxide?

Back

S₂O₃

Front

How many pairs of electrons are shared in a triple bond?

Back

Three pairs of electrons.

Front

What do covalent compounds do with electrons?

Back

They share electrons.

Front

What is the correct Lewis Dot Structure for ammonia (NH₃)?

Back

The Lewis structure shows nitrogen in the center with three hydrogen atoms bonded to it and one lone pair of electrons on nitrogen.

Front

Define 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 a single bond and a double bond?

Back

A single bond involves one pair of shared electrons, while a double bond involves two pairs of shared electrons.

Front

What is the significance of the octet rule in covalent bonding?

Back

The octet rule states that atoms tend to form bonds until they are surrounded by eight valence electrons, achieving a stable electron configuration.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are not shared equally between atoms, resulting in a molecule with a slight electrical dipole moment.

Front

What is the molecular geometry of methane (CH₄)?

Back

The molecular geometry of methane is tetrahedral.
