The incorrect statement regarding the given structure is

(A)Can be oxidized to a dicarboxylic acid with $Br_{2}$ water✓ Correct
(B)despite the presence of - CHO does not give Schiff's test
(C)has 4-asymmetric carbon atom
(D)will coexist in equilibrium with 2 other cyclic structure

Answer: (A)

Solution

For this aldose,

B r_{2}

/water oxidises only the –CHO to –COOH, giving a monocarboxylic (aldonic) acid, not a dicarboxylic acid. So statement (1) is the incorrect one. Option (1).
