Part A: Explain solubility of vitaminsFood additive E307 (alpha-tocopherol, vit. E), and ascorbic acid (vit. C) are essential nutrients in humandiet due to their antioxidant properties. They have very different solubilities. In contrast to vit. A, vit. E isinsoluble in water. It is recommended that foods rich in vitamin E be taken with fatty ingredients (think saladdressing etc).• Draw the structures of both vitamins and explain their different solubilities in water.• Draw the picture illustrating solvation of vit. C in water and describe intermolecular interactions thatfacilitate this process.What type of intermolecular interactions help vitamin E be soluble in oils (fatty acids such as linoleicacid)?Part B: Explain observed boiling pointThe two molecules shown in Fig. 1 are constitutional isomers but have drastically different boiling point. Usinga drawing and no more than 5 sentences explain how why compound B (butyramide) has higher boiling point.A OвоNH2153 °C216 °CFigure 1: Isomeric amides
