Question

Match the following

• A. A- IV B-III C-II D-V
• B. A- III B- I C-II D-IV
• C. A- V B-I C-III D-II
• D. A- IV B-I C-III D-V

Hint:

Remember the key properties of carbon allotropes that dictate their applications: \begin{itemize} \item Carbon black: Fine particle size, reinforcing agent. \item Graphite: Conductivity, layered structure, lubricant. \item Diamond: Hardness, high refractive index. \item Activated charcoal: Porosity, adsorption capacity. \end{itemize}

Answer 1

The Correct Option is D

Step 1: Understand the properties and uses of different allotropes of carbon.

Step 2: Match each allotrope with its primary application. \begin{itemize} \item A. Carbon black: A fine powder used extensively as a filler in automobile tyres (IV) to enhance strength and durability. \item B. Graphite: A good conductor of electricity and has a layered structure making it suitable for electrodes in batteries (I). \item C. Diamond: The hardest known natural material, making it ideal as an abrasive (III) for cutting and grinding. \item D. Activated charcoal: Highly porous with a large surface area, used for adsorption in air conditioning systems (V) and filters to remove impurities and odors. \end{itemize}
Step 3: Combine the matches to find the correct option.
The correct matching is A - IV, B - I, C - III, D - V. Final Answer: The final answer is $\boxed{A - IV, B - I, C - III, D - V}$
