Aliphatic or aromatic

Question

I have this exam question:

a) Log P for ibuprofen is 3.6, whereas the value for phenylacetic acid is
1.4. Use selected data from the table to estimate the hydrophobicity
constant (π) for the 2-methylpropyl group (i.e. -CH2CH(CH3)2) when
attached to an aromatic ring. Predict also log P for the ibuprofen
analogue flurbiprofen.

 

So I know what method to use to work out this answer. But from the table, there are two values, one for aromatic and one for aliphatic. Given that all the compound above have a benzene ring, would the CH3 group in ibuprofen be aromatic too? The CH3 group I am talking about is the one that branches of from COOH one. I can't upload the whole table and diagrams otherwise I would

Answer 1

No, the methyl group would not be aromatic. The aromatic ring makes the compound an aromatic, the overall compound would be classified as aromatic, but only the ring itself would display aromatic characteristics.
