Question

Each of these questions contains an Assertion followed by a reason. Read them carefully and answer the question on the basis of following options. You have to select the one that best describes the two statements.

Assertion: Carbon has the ability to form long carbon chains.

Reason: Carbon has a unique property of ability to form long straight and branched chains called catenation.

• A. If both Assertion and Reason are correct and Reason is the correct explanation of Assertion
• B. If both Assertion and Reason are correct and Reason is not the correct explanation of Assertion
• C. If Assertion is correct but Reason is incorrect.
• D. If Assertion is incorrect but Reason is correct.

Answer 1

The correct option is A

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion

Explanation of correct option:

Assertion: Carbon has the ability to combine itself, atom by atom, to form long carbon chains.

A vast amount of carbon or organic compounds are produced by self-combination.

Reason: Catenation is the formation of chain or ring molecules by the binding of one atom of an element to its another atom through covalent bonds.

For example, lengthy hydrocarbon chains and rings (benzene) are produced by the catenation of carbon.

Thus, both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

Hence, the correct answer is option (A).
