Which of the following appears to be an IR spectrum of 2-bromo-1- methylcyclohex

Question

Which of the following appears to be an IR spectrum of 2-bromo-1- methylcyclohexanol? (frequencies are indicated in a mare readable font size below the spectra) Which of the following is true for the purification of the desired product in the reaction using silica gel? The products are labeled A and B in the reaction shown B is relatively more polar and c kites from (comes out of) the column before A B is relatively less polar and elutes from the column before A B is relatively more polar and elutes from the column after A B is relatively less polar und elutes from the column after A positive Brillstein test produces a dark green precipitate produces a vivid blue-green flame results when 1-butanol is mixed with dilute aqueous potassium permanganate results in an orange color in the test solution The product of the reaction shown below results in Positive Brillstein and Jones' tests Negative Brillstein and Jones' tests Positive Brillstein test and negative Jones' test Positive

Explanation / Answer

22) B (-OH absorption takes place at 3600-3650 cm-1)

23) B (-OH is more polar than CO, so CO comes out first)

24) B

25) A
