SIngle, Double, Triple Covalent Bonds

Front

What is a single covalent bond?

Back

A single covalent bond is formed when two atoms share one pair of electrons.

Front

What is a double covalent bond?

Back

A double covalent bond is formed when two atoms share two pairs of electrons.

Front

What is a triple covalent bond?

Back

A triple covalent bond is formed when two atoms share three pairs of electrons.

Front

How many electrons does hydrogen need to achieve stability?

Back

Hydrogen needs 2 electrons in its valence shell to be stable.

Front

What is the bond type in a hydrogen molecule (H2)?

Back

The bond type in a hydrogen molecule (H2) is a single covalent bond.

Front

What makes a molecule polar?

Back

A molecule is polar if there is a nonbonding pair on the central atom or if there are different types of elements bonded to the central atom.

Front

What is a nonpolar molecule?

Back

A nonpolar molecule is one where all atoms bonded to the central atom are the same and there are no nonbonding pairs.

Front

Give an example of a molecule with a double covalent bond.

Back

An example of a molecule with a double covalent bond is oxygen (O2).

Front

Give an example of a molecule with a triple covalent bond.

Back

An example of a molecule with a triple covalent bond is nitrogen (N2).

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have an uneven distribution of charge, while nonpolar molecules have an even distribution of charge.
