Question

Substance X is a molecular compound and is not an acid nor a base. Based just on this information, what can you determine about substance X? Check all that apply.
(A) X is soluble in water.
(B) X is insoluble in water.
(C) X is an electrolyte.
(D) X is not an electrolyte.

Answer 1

Answer: The correct answer is Option A, Option B and Option D.

Explanation:

Molecular compound are defined as the compounds which are formed by the sharing of electrons between the atoms. They are also known as covalent compounds. They are of two types:

• Polar covalent compound: This compound is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond. For Example: $CO_2,NO_2$ etc..
• Non-polar covalent compound: This compound is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example: $N_2,O_2$ etc..

We know that: Like dissolves like. This means that polar solvent will dissolve polar molecules and non-polar solvent will dissolve non-polar molecules

Water is a polar compound. So, it will dissolve only polar molecules.

The given substance 'X' is a molecular compound. It may be polar or non-polar.

So, it may be soluble in water or may not be soluble.

Electrolyte are defined as the compound which conduct electricity when dissolved in water. They conduct electricity because of the ions they dissociate into.

Thus, substance 'X' is not an electrolyte.

Hence, the correct answer is Option A, Option B and Option D.
