Expert Solution

Explanation:

"Since you have asked multiple questions, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question."

Compound 1 has a very high melting and boiling point, while Compound 2 has a very low melting and boiling point. Likewise, although Compound 2 has low electrical conductivity as a liquid, Compound 1 exhibits strong electrical conductivity both as a liquid and in an aqueous solution. These characteristics point to Compound 1 being most likely ionic and Compound 2 being most likely molecular.

Therefore, the correct answer is C) Compound 1 is ionic, and compound 2 is molecular.
