Incorrect statement about given carbohydrate is

1. Above compound is a reducing sugar
2. Above compound undergo mutaritation
3. Above compound is a non-reducing sugar
4. Above compound has a glycosidic linkage

Correct answer: Above compound is a reducing sugar

Solution

The correct statement is that the compound is a reducing sugar because it has a free anomeric carbon capable of opening to the aldehyde/ketone form. That same free anomeric center also allows mutarotation, so the claim that it is non-reducing is the incorrect one.
