The correct Answer is:
To determine the ratio between hydrogen and oxygen in carbohydrates, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Carbohydrates**: Carbohydrates are organic compounds made up of carbon (C), hydrogen (H), and oxygen (O). They are classified into different types, with monosaccharides being the simplest form. 2. **Basic Formula of Monosaccharides**: The general formula for monosaccharides is given as C_n(H_2O)_n, which indicates that for every carbon atom, there are two hydrogen atoms and one oxygen atom. This can also be expressed as C_nH_(2n)O_n. 3. **Analyzing the Ratio**: From the formula C_nH_(2n)O_n, we can see that the number of hydrogen atoms (H) is always double the number of oxygen atoms (O). Therefore, the ratio of hydrogen to oxygen in monosaccharides is H:O = 2:1. 4. **Examples**: - For glucose, the molecular formula is C6H12O6. Here, the number of hydrogen atoms (12) is double that of the oxygen atoms (6), confirming the 2:1 ratio. - For fructose, the molecular formula is C5H10O5. Again, the number of hydrogen atoms (10) is double that of the oxygen atoms (5), which also confirms the 2:1 ratio. 5. **Conclusion**: Based on the analysis and examples provided, we can conclude that the ratio of hydrogen to oxygen in carbohydrates is 2:1. ### Final Answer: The ratio between hydrogen and oxygen in a carbohydrate is **2:1**. ---
