Polarity: Ibuprofen vs Acetanilide

Hello,
Comparing ibuprofen to acetanilide, which one would you expect to have a greater polarity? I've been reading that the alkyl group on ibuprofen would significantly reduce its polarity, and am wondering your guys' thoughts. Also, ibuprofen has a much lower solubility in water, but I don't know if that alone is enough to decide if it's more nonpolar.

The amide group is more polar than the carboxylic group, and acetanilide has a lower log P value than ibuprofen, which is also consistent with it being more soluble.

Hi ozo,
can you please explain the significance of the log P value?

I found references for a log P value of 1.16 for acetanilide, and 1.27 to 1.37 for ibuprofen.
Lower values indicate more hydrophilic and more polar.
