Q: Which of the following test is used specifically for identification of keto sugars?
  • A. Benedict's Test
  • B. Seliwanoff's Test
  • C. Fehling's Test
  • D. Molisch Test
Correct Answer: Option B - Seliwanoff's test is a chemical test which distinguishes between aldose and ketose sugars . If the sugar contains a ketone group it is a ketose. If a sugar contains an aldehyde group, It is an aldose. This test relies on the principle that, when heated, ketoses are more rapidly dehydrated than aldoses.
