Chemical Bonding

Question 1

Intramolecular bond

Answer 1

A bond which occurs between atoms within a molecule

Question 2

Electronegativity

Answer 2

A measure of the tendency of an atom to attract a bonding pair of electrons

Question 3

Covalent bond

Answer 3

A sharing of at least one pair of electrons by 2 non-metal atoms

Question 4

Non-polar covalent (pure covalent)

Answer 4

An equal sharing of electrons

Question 5

Polar covalent

Answer 5

Unequal sharing of electrons leading to a dipole forming (as a result of electronegativity difference)

Question 6

Ionic bond

Answer 6

A transfer of electrons and subsequent electrostatic attraction

Question 7

Metallic bonding

Answer 7

the bond between a positive kernel and a sea of delocalized electrons

Question 8

Intermolecular force

Answer 8

A weak force of attraction between molecules, ions, or atoms of noble gases

Question 9

London forces (Induced dipole)

Answer 9

Intermolecular forces that occur between all particles. Occur when a dipole is induced, very weak interactions. Between NON-POLAR molecules

Question 10

Dipole-dipole interactions (stronger)

Answer 10

when 2 permanent dipole molecules come near each other, the partially negative side of 1 molecule attracts the partially positive side of the other. Between POLAR molecules

Question 11

Hydrogen bonds (strongest)

Answer 11

Type of Dipole-dipole interaction. Only occurs when a hydrogen atom is “shared” between 2 small, highly electronegative atoms with at least 1 lone pair of electrons; Oxygen, Nitrogen, and Fluorine. Between POLAR molecules
