Answer 2

Answer: Their general formula: $C_{x}(H_{2}O)_{y}$ describes that they are hydrates of carbon.

Explanation:

• Carbohydrates are macromolecules with the general formula $C_{x}(H_{2}O)_{y}$ . Carbohydrates are hydrates of carbon and thus generally conform to the formula. They have Hydrogen  and Oxygen in the same ratio as in water. Hydrates of carbon are referred to as Carbohydrate.  
• However, all carbohydrates do not abide by the same formula. There are exceptions like- 2-deoxyribose which do not fit under this formula but are carbohydrates.
• Carbohydrates have C, H, O in the ratio 1:2:1.
• Therefore, this combination is apt for defining carbohydrates and describes the chemical group correctly.
