Which of the following statement is wrong regarding the reducing ability of sugar.

  1. The aldehyde group of saccharide is responsible for its it reducing properties.

  2. Ketoses are not reducing sugar because they are not aldehyde

  3. A methyl glucoside is not a reducing sugar

  4. D glucose predominantly in a cyclic hemiacetal form but is a reducing sugar through the acyclic form with which the hemiacetal is in equilibrium.
