1. From Chem text: Read p 484-486 regarding Vitamin C, Vitamin A, and
vitamins and solubility. Then:
a) Text indicates that Vitamin C is highly polar. Redraw the organic
structure of Vitamin C (shown on p 484). On your diagram, use a
highlighter to highlight the portions of the molecule that is likely
to be partially negative (charged). Then add to your drawing
diagrams of water molecule to depict the hydration of Vitaminc C by
water molecules.
b) Redraw the organic structure of Vitamin A. Highlight the negative
portions of the molecule then write a brief explaining why Vitamin A
is insoluble in water. Reference your diagram in you briefing.
