Based on the types of bonding in the following compunds, explain why you would expect: 1) calcium chloride (CaCl2) to be soluble in water 2) Ethane (CH3CH3) to be insoluble in water

Answer 1

Calcium chloride is a polar bond(ionic). Water is polar. Like dissolves like.
CH3CH3 is a non-polar compound made up of covalent bonds. It isn' very soluble in a polar solvent such as water.
