Correct Answer - Option 3 : Sucrose

The correct answer is Sucrose.

  • Chemically, cane sugar is sucrose.

  • Sucrose is a disaccharide consisting of one glucose and one fructose molecule in equal ratio.
  • The formula of cane sugar is C₁₂H₂₂O₁₁.
  • It appears as white odourless crystalline or powdery solid and is denser than water.
  • Maltose, sucrose, lactose are disaccharides made up of two monosaccharides.

  • Carbohydrates:
    • Carbohydrates are organic compounds in which the ratio of Carbon, Hydrogen and Oxygen is 1: 2 : 1.
    • Carbohydrates are classified into three major groups:
      • Monosaccharides: These are the simple sugar made up of single polyhydroxy or ketone unit.
      • Most abundant monosaccharides found in nature are glucose.
      • Triose, tetrose, pentoses, heptoses are the type of monosaccharides.
      • Oligosaccharides: When 2 to 10 monosaccharides join together they form oligosaccharides. Maltose, sucrose, lactose are disaccharides made up of two monosaccharides.
      • Polysaccharides: These are the compounds of sugar which are formed due to joining a large number of monosaccharide. Some examples of polysaccharides are starch, glycogen, cellulose, chitin, etc.
