Unit 4 Chemical Bonds Test #2: Concepts 4-6

Front

What is a double bond?

Back

A double bond is a type of chemical bond where two pairs of electrons are shared between two atoms.

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

What type of bond is formed when two atoms share electrons?

Back

Covalent bond.

Front

What is the molecular shape of a molecule with two bonding pairs and two lone pairs of electrons?

Back

Bent.

Front

What type of intermolecular force is responsible for the high surface tension of water?

Back

Hydrogen bonds.

Front

What is an intramolecular bond?

Back

An intramolecular bond is a bond that occurs within a molecule, such as covalent, ionic, or metallic bonds.

Front

Which bond is not considered an intramolecular bond?

Back

Hydrogen bond.

Front

What is hydrogen bonding?

Back

Hydrogen bonding is a type of attractive interaction between a hydrogen atom bonded to a highly electronegative atom and another electronegative atom.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons.

Front

What is the significance of molecular shape in chemistry?

Back

Molecular shape affects the physical and chemical properties of a substance, including reactivity, polarity, and phase of matter.
