The predominant intermolecular forces present in ethyl acetate, a liquid, are:

The predominant intermolecular forces present in ethyl acetate, a liquid, are:
  1. London dispersion and dipole-dipole
  2. hydrogen bonding and London dispersion
  3. Dipole-dipole and hydrogen bonding
  4. London dispersion, dipole-dipole and hydrogen bonding

Solution

Ethyl acetate is polar molecule so dipole-dipole interaction will be present there. Also, hydrogen is not attached to electronegative element so, hydrogen bonding is not possible.

Hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces.
