Answer 1

Maltose:

1. Maltose, also known as maltobiose or malt sugar, is a disaccharide made up of two glucose units connected together by a bond.
2. It has a chemical formula ${\mathrm{C}}_{12}{\mathrm{H}}_{22}{\mathrm{O}}_{11}$.

Reducing sugar:

1. Maltose has two glucose units, and the free aldehyde group can be produced in solution via the second glucose unit.
2. The reaction is given below:

Hence, Maltose is a reducing sugar.
