The correct observation in the following reaction is: Sucrose → Cleavage   ( Hydrolysis ) Gly   cosidic   bond A + B → Reagent Seliw   anoff ?

Options

  1. AFormation of blue colour
  2. BGives no colour
  3. CFormation of red colour
  4. DFormation of violet colour

Correct answer

C. Formation of red colour

Step-by-step solution

Seliwanoff reagent → [ Resorcinol + Conc. HCl ] 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. Ketoses show red colour with Seliwanoff Reagent.
