The carbohydrate which does not react with ammonical $\mathrm{AgNO}_3$ solution is

The carbohydrate which does not react with ammonical $\mathrm{AgNO}_3$ solution is
  1. Sucrose
  2. Maltose
  3. Lactose
  4. Fructose

Solution

In disaccharides, if the reducing groups of monosaccharides i.e., aldehydic or ketonic groups are bonded, these are non-reducing sugar e.g., sucrose. On the other hand, sugars, in which these functional groups are free, are called reducing sugars for example, maltose and lactose.
