Question

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

• A. London dispersion, dipole - dipole and hydrogen bonding
• B. Hydrogen bonding and London dispersion
• C. Dipole-dipole and hydrogen bonding
• D. London dispersion and dipole-dipole

Answer 1

The correct option is D London dispersion and dipole-dipole

The predominant intermolecular forces present in ethyl acetate liquid is London dispersion and dipole-dipole interaction. Ethyl acetate is a polar molecule, therefore, dipole-dipole interaction will be present there.
Hence, option $\left(d\right)$ is correct.
