the Seliwanoff's test result of galactose and TLC?

Question

and Do the fructose can move in TLC (sol. n-Butanol:acetic acid :watwr =4:1:1)

Answer 1

Seliwanoff's test is most diagnostic for fructose, though other sugars react after a time delay. The reagent is a solution of resorcinol (1,3-dihydroxybenzene) in water. One adds the sugar and acid. Acid converts fructose to 2-hydroxymethylfurfural, which condenses with resorcinol to form a red product. Acid eventually hydrolyzes sucros to glucose and fructose, which reacts. Other sugars like galactose give lesser amounts of the furfural.
