In this sequence of reaction three times aldol reaction occurs first than cross Cannizaro reaction takes place as follows

C H_{3} - C H O + 3 H C H O O H^{-} Aldol condensation 3times C H_{2} O H_{3} - C - C H O

C H_{2} O H_{3} - C - C H O O H^{-} Cross cannizzaro reaction C - C H_{2} O H_{4}

In this sequence of reaction three times aldol reaction occurs first than cross Cannizaro reaction takes place as follows CH3​−CHO+3HCHOOH−Aldol condensation 3times ​CH2​OH3​−C−CHO CH2​OH3​−C−CHOOH− Cross cannizzaro reaction ​C−CH2​OH4​

In this sequence of reaction three times aldol reaction occurs first than cross Cannizaro reaction takes place as follows
$C H_{3} - C H O + 3 H C H O O H^{-} Aldol condensation 3times C H_{2} O H_{3} - C - C H O$
$C H_{2} O H_{3} - C - C H O O H^{-} Cross cannizzaro reaction C - C H_{2} O H_{4}$
