Question

The table below shows properties of two compounds at standard pressure. Which statement classifies the two compounds? 1)Both compounds are ionic, 2)Both compounds are molecular, 3) Compound 1 is ionic, and compound 2 is molecular, 4)Compound 1 is molecular, and compound is ionic

Answer 1

Answer:

answer of this question is option. 3. compound 1 is ionic ,and 2 is molecular

Answer 2

Compound 1 is ionic and compound 2 is molecular. The correct option is 3) Compound 1 is ionic, and compound 2 is molecular

From the question,

We are to classify the compounds according to the information provided in the table

First,

We will list the properties of ionic and molecular compounds

Properties of ionic compounds

• The exist as solid at room temperature.
• They generally have high melting and boiling temperatures.
• They are good electrical conductors when molten or in solution.

Properties of molecular compounds

• They can exist as solid, liquid or gas.
• They generally have low melting and boiling temperatures.
• They are poor electrical conductors.

In the given table,

Compound 1 has high melting and boiling points, and it is a good electrical conductor. Therefore, compound 1 is ionic

Compound 2 has low melting and boiling points, and it is a poor electrical conductor. Therefore, compound 2 is molecular

Hence, Compound 1 is ionic and compound 2 is molecular. The correct option is 3) Compound 1 is ionic, and compound 2 is molecular
