Step 1
Which line in the table shows the solubilities of these compounds in water and in oil?
Answer
To determine the solubility of the flavours in water and oil, we must consider their structure and the nature of their functional groups.
- Cucumber Flavour: Typically has a high soluble nature in water due to its hydroxy groups, making it hydrophilic.
- Vanilla Flavour: It usually contains a high number of aromatic rings which makes it more soluble in oil (lipophilic) than in water.
- Ginger Flavour: Contains hydroxyl groups, suggesting good water solubility.
- Orange Flavour: Also hydrophobic due to its terpene structure, thus more soluble in oil.
Based on this analysis, the combinations are as follows:
- Cucumber and ginger would likely be water soluble, while vanilla and orange are more oil soluble.
This leads to the conclusion: C (ginger and vanilla, orange and cucumber) accurately reflects this solubility preference.
