You will analyze the purity of propyl-p-tolyl ether by gc. assuming that some n-pr-i (starting material) is present, which compound, n-pr-i or propyl-para-tolyl ether (product), eluted from the gas chromatography column first (had the shorter retention time). explain the order of compound elution in terms of molecular structure and boiling point. 5. using the same experimental procedure as in this experiment, explain why using para-bromotoluene and sodium n-propanoxide (which in principle, would give the same product) would not work. assign all the 'h-nmr and 13c-nmr peaks on the spectra of propyl-para-tolyl ether p 325-326.
