प्रश्न
Cannizaro’s reaction is not given by ______.
विकल्प
\[\ce{HCHO}\]
\[\ce{CH3CHO}\]
उत्तर
Cannizaro’s reaction is not given by \[\ce{CH3CHO}\].
Explanation:
\[\ce{CH3CHO}\] will not give Cannizzaro’s reaction because it contains a-hydrogen while other three compounds have no a-hydrogen. Hence, they will give Cannizzaro’s reaction.
