2) See, ionic compounds are good conductor of electricity. And covalent Compounds are poor conductor of electricity.
Here only sucrose is covalently bonded compounds .
Hence, correct option is : "sucrose".
3) Compounds having ionic character are good electrolyte.
Hence, options is : "HCl"

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...
