We performed the Friedel Crafts alkylation and one of the products was determined to be propyl p-xylene, molecular formula of C11H16. The CNMR data shows 10 shifts: 148,135,131,128,127,125,30,25,24,and 18. Im having trouble assigning which carbons are which within the molecule. Any help would be appreciated! Thanks.

Did u searched for this?
I think it is available in basic spectroscopic book.
You may get lot of stuff from google itself.
Use chemdraw to predict which shift belongs to which carbon.
