For the reaction below, focus only on 2-methyl-2-butanol
(starting material) and 2-chloro-2-methylbutane (desired product).
We will not analyze HCl or H2O by IR.
From the two IR spectra below, identify which spectrum belongs
to which molecule. Then label the IR spectrum with the molecule’s
characteristic IR peaks. Highlight or place a box around the most
characteristic peak in the starting material’s IR. You do not need
to label the fingerprint region.
