Among the following mixture, maximum dipole-dipole interaction is present in:
Among the following mixture, maximum dipole-dipole interaction is present in:
- A. benzene and ethanol
- B. acetonitrile and acetone
- C. \( K C l \) and water
- D. benzene and carbon tetra chloride
Step-by-step solution
Both acetonitrile and acetone are polar molecules with significant dipole moments (acetonitrile ~3.9 D, acetone ~2.9 D) and no hydrogen bonding, leading to strong dipole-dipole interactions in the mixture. Option A includes nonpolar benzene, reducing dipole-dipole interactions. Option C involves ion-dipole and hydrogen bonding, which are stronger than dipole-dipole but not the focus. Option D consists of two nonpolar molecules with only London dispersion forces.
