Final answer:
Benzophenone is more polar than biphenyl due to the presence of the polar keto group which introduces a dipole moment, while biphenyl lacks such polar functional groups.
Step-by-step explanation:
When comparing the polarity of benzophenone and biphenyl, it is important to consider the structural differences that contribute to the overall polarity of each compound. Benzophenone contains a keto group (C=O) attached to two benzene rings, making it a more polar molecule. The keto group introduces differences in electronegativity, which generates a dipole moment. On the other hand, biphenyl consists of two benzene rings connected directly to each other without any polar functional groups, making it less polar than benzophenone.
The polarity of a molecule is influenced by functional groups and their ability to create dipole moments. Since benzophenone has a functional group that is polar, while biphenyl does not, benzophenone is indeed more polar than biphenyl, thus the correct answer is: 1) Yes.
