(C) The statement that aldose or ketose sugars in alkaline medium do not isomerize is incorrect.In an alkaline medium,aldose and ketose sugars undergo a reversible isomerization process known as the $Lobry \ de \ Bruyn-van \ Ekenstein \ rearrangement$.For example,in a dilute solution of $NaOH$,glucose (an aldose) undergoes isomerization to form an equilibrium mixture of $D$-glucose,$D$-mannose,and $D$-fructose.Therefore,option $C$ is the incorrect statement.
