Directions: In the following questions, a statement of assertion (A) ...
Assertion and Reason:Assertion: Carbon compounds can form chain, branched, and ring structures.
Reason: Carbon exhibits the property of catenation.
The given statement involves an assertion and a reason. Let's analyze the assertion and reason individually to determine their validity.
Assertion: Carbon compounds can form chain, branched, and ring structures.
- This assertion is true. Carbon is unique because it can form covalent bonds with other carbon atoms, allowing for the formation of long chains, branched structures, and closed rings. This property is known as catenation.
Reason: Carbon exhibits the property of catenation.
- This reason is also true. Catenation is the ability of an element, particularly carbon, to form covalent bonds with other atoms of the same element. Carbon has four valence electrons, allowing it to form up to four covalent bonds. This property of carbon enables the formation of various structures, including chains, branches, and rings.
Conclusion:Both the assertion and the reason are true. Furthermore, the reason (carbon's catenation property) provides a correct explanation for the assertion (formation of chain, branched, and ring structures). Therefore, option A is the correct answer.
Note: The key here is to understand that carbon's ability to form covalent bonds with other carbon atoms is what allows for the formation of different structures. This property is known as catenation, and it is the reason behind carbon compounds' versatility in forming chains, branches, and rings.
