Step by Step Solution

Step 1: Solubility and polarity

Polarity is one of the factors that help in making out the solubility of a particular substance. Polar compounds solubilize in water, whereas non-polar compounds solubilize in organic solvents.

Step 2: Solubility of compound a

Vitamin E contains a hydroxyl group and a large non-polar group. The compound is water-insoluble because of the large non-polar group that dominates over the hydroxyl group. The presence of the large non-polar group makes it soluble in an organic solvent.

Solubility of compound a

Hence, vitamin E is insoluble in water and soluble in an organic solvent.

Step 3: Solubility of compound b

The multiple hydroxyl groups in the vitamin lead to the compound having hydrogen bonding. The compound is water-soluble because of the hydroxyl groups that dominate the non-polar groups.

The polarity of the compound makes it insoluble in organic solvents and soluble in water.

Solubility of compound b

Hence, the vitamin is soluble in water and insoluble in an organic solvent.
