a) at approximately what location is the carbonyl peak
of cyclohexanone on the IR spectrum?
b) at approximately what location is the OH peak of cyclohexanol on
the IR spectrum?
c) is it jagged or rounded?
d) what two classes of compounds can primary alcohols be
oxidized?
e) what determines which product results from such oxidation?
Ans. (a) carbonyl peak of cyclohexanone is observed at around 1715cm-1.
(b) OH peak appears as strond and broad signal at around 3400cm-1.
(c) OH peak is rounded in shape
(d) primary alcohols can be oxidized to aldehyde by PCC and it can be oxidized to carboxylic acid by K2Cr2O7, jones reagent etc.
(e) product can be analyzed by IR, if broad OH peak at a range of 2500 cm-1 to 3300cm-1 that means carboxylic acid form and if OH peak disappear then it is oxidized to aldehyde.
