Answer to Question #140712 in General Chemistry for Javier

Question

Water is a polar solvent; CCl4 is a nonpolar solvent. In which solvent more likely to be soluble?

Sugar, Polar

Water
Or
carbon tetrachloride

Answer 1

Sugar soluble in water

Cause:

Sugar is a polar compound , in the solid state of it Hydrogen bond strongly binds the molicules of sugar together.

The polar compound will get soluble in a solvent when solvent molicules forms more strong hydrogen bond than that exist between different molicules of sugar.

In water molicule the polar ^δ–O—H^δ+ bond is responsible for hydrogen bond formation.

Water can form extensive amount of Hydrogen bond with sugar molicules.

Being a non polar solvent and low polarity difference between Cl and C atom C—Cl bond in CCl4 is unable to form hydrogen bond. That's why sugar can't be soluble in CCl4.
