Question

The compound is impure substance
A. True
B. False

Answer 1

Hint: In order to answer this question we should be having a basic idea about what actually the compound means. Knowing the proper definition of compounds which can easily compare them with the question that is being given.

Complete answer:
Chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds.
Two atoms of the same element mounted in a molecule does not form a chemical compound since this would require two different elements.
Compounds of pure substances as all the particles in the compounds are of similar type.
The classification of matter is as follows:
\[\begin{align}
 & \text{cation + anion = compound} \\
 & \text{metal + non-metal = ionic compound} \\
 & \text{non-metal + non-metal = molecular compound } \\
\end{align}\]
Pure matter exists in 2 states; elements and compounds. Impure matter is known as a solution or a mixture.
As we can see that the answer to this question is false so Option B is the correct option.
To know more about the compounds let us have an example. Hydrochloric acid is a compound of hydrogen and chlorine. It is a pure substance as all the particles of hydrochloric acid are of the same type.

Note:
Do not get confused between compounds, molecules and solutions. Molecules are the units out of which compounds are made. We can say that a compound consists of molecules. A solution is formed when a solvent is added to a compound, thus it cannot be a pure substance.
