The predominant intermolecular forces present in ethyl acetate, a liquid, are:
Options
- ALondon dispersion and dipole-dipole
- Bhydrogen bonding and London dispersion
- CDipole-dipole and hydrogen bonding
- DLondon dispersion, dipole-dipole and hydrogen bonding
Correct answer
A. London dispersion and dipole-dipole
Step-by-step 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.
