The correct Answer is:
To determine the relationship between neopentane and n-pentane, we need to analyze their structures and classify them accordingly. Here’s a step-by-step solution: ### Step 1: Understand the Structures - **n-Pentane** is a straight-chain alkane with five carbon atoms. Its structure can be represented as: ``` CH3-CH2-CH2-CH2-CH3 ``` - **Neopentane** (also known as 2,2-dimethylpropane) has a branched structure with the same number of carbon atoms. Its structure can be represented as: ``` CH3 | CH3- C - CH3 | CH3 ``` ### Step 2: Count the Carbon and Hydrogen Atoms - Both n-pentane and neopentane contain 5 carbon atoms (C) and 12 hydrogen atoms (H). - n-Pentane: C5H12 - Neopentane: C5H12 ### Step 3: Identify the Type of Isomerism - Since both compounds have the same molecular formula (C5H12) but different structural arrangements, they are classified as **isomers**. - Specifically, they are **chain isomers** because the difference arises from the arrangement of the carbon chain (one is straight and the other is branched). ### Step 4: Conclusion - The relationship between neopentane and n-pentane is that they are **chain isomers**. ### Final Answer The correct relation between neopentane and n-pentane is that they are **chain isomers**. ---
