An organic compound answers Molisch's test as well as Benedict's test, but it does not answer Scliwanoff s test. Most probably, it is

Options

  1. Asucrose
  2. Bprotein
  3. Cfructose
  4. Dmaltose

Correct answer

D. maltose

Step-by-step solution

Molisch's test is used to detect all kinds of carbohydrates. The Benedict test identifies reducing sugars (mono saccharides and some disaccharides) which have free ketone or aldehyde functional group. Scliwanoff's test is used for detection of fructose or keto group in sugar solution. Therefore, give negative test for maltose. Hence, organic compound is maltose.
