Answer 1

Answer #1

Ketone group undergoes reduction in NaBH₄ and produces hydroxy derivative as shown below:

The reaction described converts a ketone to an alcohol.

Therefore, the peak in the IR spectrum of product will be missing the peak corresponds to ketone.

The normal frequency for a ketone peak from cyclohexanone is 1715 cm^-1.

The S–H stretching absorption in the IR spectrum of thiols is less intense and occurs at lower frequencies (~2550 cm-1) compared to the O–H stretching absorption of alcohols (3200–3600 cm- 1). Use what you know about influences on IR stretching frequency to explain why this is the case.

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. For the reaction below, focus only on 2-methyl-2-butanol...
