WebQuestion: Classify the following compounds as polar or non-polar: a) biphenyl b) benzoic acid c) 2-aminobenzoic acid d) 4-aminobenzoic acid I'm fairly sure a is non-polar. I thought b would be polar but I keep getting conflicting responses because benzene ring "cancels out the polarity of the carboxylic acid." I get that it is somewhat both but ... WebYes, there are two spots where hydrogen bonding can occur in the second molecule whereas there is only one in the first molecule. Therefore, it is more polar. When determining polarity, the order of importance is hydrogen bonding>dipole-dipole>LDFs. Since the only thing that changes is the number of hydrogen bonding locations, and …
