1. On the skeletal structure above (see link below), encircle and name the key functional groups.
2. Describe the polarity of each functional group, and the overall solubility of the molecule in water and hexane. Indicate what kind of IMF interactions are expected for each functional group with the solvent.
3. Are there functional groups which can gain or lose H ? Which ones? If so, how will this affect solubility?

Please explain what is the chemical reactions and its principles and also explain why the diluted juice (water + calamansi (it is a citrus fruit here in the Philippines, it's like a lime but circle in shape and smaller) changed in color (from pale yellow it turns into dark orange) when the supernatant (water + steel scrubber (The liquid turns into darker shade due to rust) was mixed with the diluted juice. Thank you so much, can you please also put references since it is necessary for our activity.
