Question

Which of these statements is correct about wood and common salt?

Answer 1

Answer: Option (C) is the correct answer.

Explanation:

Minerals are inorganic substances which have certain characteristic shape or structure along with homogeneous chemical composition.

It is not necessary that a mineral should be formed under the ground.

Substances which have carbon atoms in their structure are called organic compounds.  The structure of wood has carbon atoms attached thus, wood is an organic compound.

Therefore, we can conclude that common salt is a mineral because it has a definite crystal structure but wood is not a mineral because it is organic.

Answer 2

Answer:

The correct answer is option C, Common salt is a mineral because it has a definite crystal structure but wood is not a mineral because it is organic

Explanation:

Minerals are basically of two types organic and inorganic. Most of the minerals found in the form of rock ores are inorganic minerals while organic minerals are formed from the decomposition of organic matter. All organic minerals have carbon in their chemical structure. Some common example of organic minerals are petroleum, fossil products, salts of organic acids etc.  

From the above explanation, it is clear that NaCl (salt) is a form of mineral but wood is an organic matter which may result into minerals after decomposition but in the form of wood , it cannot be considered as a mineral.
