A student was planning to synthesize 2-chloro-3-methylbutane from 3-methyl-2-butanol using concentrated HCl, similar to the reaction you did. When the experiment was carried out, the product isolated was 2-chloro-2-methylbutane. Explain these results by showing a plausible mechanism for the formation of 2-chloro-2-methylbutane under these reaction conditions. (Hint: it is an SN1 reaction, but think about what can happen to the carbocation intermediate that we learned about in lecture to cause that product to form.)

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.
