The incorrect statement regarding the given structure is

can be oxidized to a dicarboxylic acid with $$\mathrm{Br}_2$$ water
despite the presence of $$-\mathrm{CHO}$$ does not give Schiff's test
will coexist in equilibrium with 2 other cyclic structure
has 4 asymmetric carbon atom

Explanation

The given structure is of glucose.

Glucose does not give Schiff test due to absence of aldehyde group in ring structure, glucose on reaction with $$\mathrm{Br}_2 / \mathrm{H}_2 \mathrm{O}$$ give gluconic acid which is mono carboxylic acid.
