Which of the following reagents can be used to oxidise primary alcohols to aldehydes?
(i) in anhydrous medium.
(ii) in acidic medium.
(iii) Pyridinium chlorochromate.
(iv) Heat in the presence of at 573K
Answers (1)
The answer is the option (i), (iii), and (iv). The complete oxidation of primary alcohols results in the formation of carboxylic acid unless a mild oxidising agent is added to terminate the reaction at the aldehyde formation step. The most common mild oxidising agent used is (Pyridinium chlorochromate). Some other compounds used for this purpose are
in an anhydrous medium and Heat in the presence of
at 573K. So, the correct answers are an option (i), (iii), and (iv)
