Answer
a) Dipole-dipole
b) London Dispersion
c) London Dispersion
d) Hydrogen Bonding
Work Step by Step
a) The molecule has a dipole moment so dipole-dipole
b) The molecule is nonpolar so its strongest intermolecular force is London dispersion
c) The molecule is nonpolar so its strongest intermolecular force is London dispersion
d) This molecule is polar and it has oxygen and hydrogen so it is capable of hydrogen bonding
