For example, if I was to perform the following reaction:

$\ce{CH3CHCH2 + HBr -> CH3CHBrCH3 + CH3CH2CH2Br}$

How would I quantitatively determine the relative yield of the primary and secondary alkyl halides?

Would IR or UV/Vis spectrscopy be able to differentiate between them, or would I have to utilize reactions such as substitution with hydroxyl then oxidation to form ketones and carboxylic acids to differentiate between the two?

    $\begingroup$ 1H NMR would show the relative yield by comparing the integration of the CHBr proton and the CH2Br protons.. IR or UV/Vis will not do this. $\endgroup$ – Waylander Mar 13 at 7:27
