In liquid propanol,

Question

CH3CH2CH2OH
which intermolecular forces are present?
a)Only dispersion and dipole-dipole forces are present.

b)Dispersion, hydrogen bonding and dipole-dipole forces are present.
c)Only hydrogen bonding forces are present.

d)Only dipole-dipole and ion-dipole forces are present.

Answer 1

All molecules have dispersion forces.
H atoms of one atom attracted to a highly electronegative element (F, Cl, O) of another provides hydrogen bonding.
Molecules that have one end more polar than the other are dipoles.
