ANSWER:
Solution 2P:
Here, we are going to Predict the products of the reactions of the following compounds with chromic acid and also with PCC.
PCC is Pyridinium chlorochromate (PCC) having a complex of chromium trioxide with pyridine and HCl. It is an oxidant. PCC oxidizes most primary alcohols to aldehydes in excellent yields. PCC is soluble in nonpolar solvents such as dichloromethane which is an excellent solvent for most organic compounds. PCC can also serve as a mild reagent for oxidizing secondary alcohols to ketones.
Chromic acid, H2CrO4, is a strong acid and is a reagent for oxidizing alcohols to ketones and carboxylic acids.
(a) cyclohexanol
Step 1:
The conversion of cyclohexanol to cyclohexanone in presence of PCC and chromic acid is given below:
