Two-organic substances are labelled K and L if K gave a blue-black colour with iodine solution and L gave a deep red precipitate with Million’s reagent, it can be concluded that
-
K is a carbohydrate and L is a protein
- K is alkaline and L is acidic
- K is unsaturated and L is a reducing sugar
- K is a reducing agent and L is an amino acid
The correct answer is: A
Explanation
Substance K can be said to be Carbohydrate because starch (carbohydrate) when reacted with iodine, gives a blue-black colour while Protein (substance L) reacts with a Million's reagent to give a deep-red ppt. Hence, the correct answer is A
