NTA AbhyasNTA Abhyas 2020Aldehydes Ketones and Carboxylic Acids
Solution:
In this sequence of reaction three times aldol reaction occurs first than cross Cannizaro reaction takes place as follows
$CH _3- CHO +3 HCHO \xrightarrow{ OH ^{-} \text {Aldol condensation 3times }} CH _2 OH _3- C - CHO$
$CH _2 OH _3- C - CHO \xrightarrow{OH ^-\text { Cross cannizzaro reaction }} C - CH _2 OH _4$
