Identify the intermolecular forces holding the molecules together in each sample. CH3NH2 _______________________________________
omeli [17]

Answer:

CH3NH2 : Hydrogen bonding and London dispersion forces

F2 : Hydrogen bonding, dipole-dipole and London dispersion forces

NOF : Dipole-dipole forces

C2H6 : London dispersion forces

H2O : Hydrogen bonding and London dispersion forces

Increasing order of boiling point:

F2

C2H6

NOF

CH3NH2

H20

Explanation:

London dispersion forces exist in all substances

CH3NH2 : The hydrogen bonding in the amine group and the assymetry of the molecule makes the hydrogen bonding and dipole-dipole bonds from the methyl group.

F2 : The bond is non polar because its a homonuclear bond

NOF : Dipole-dipole forces due to difference in elecronegativity between all the atoms involved and assymetry

C2H6 : London dispersion forces because all dipole-dipole forces are cancelled out due to the symmetry of the molecule

H2O : Hydrogen bonding between hydrogen and oxygen and the assymetry of the molecule

Order of boiling points: London dispersion forces, followed by dipole-dipole forces and hydrogen bonding is the strongest
