Question: Which of the following is an example of chain isomerism?
Options:
Pentane and 2-methylbutane
Butene and Butyne
Ethanol and Dimethyl ether
Acetic acid and Propanoic acid
Correct Answer: Pentane and 2-methylbutane
Solution:
Pentane and 2-methylbutane differ in the arrangement of carbon atoms, thus showing chain isomerism.

Questions & Step-by-Step Solutions
Which of the following is an example of chain isomerism?
Step 1: Understand what chain isomerism means. It refers to compounds that have the same molecular formula but different arrangements of carbon atoms in their structure.
Step 2: Identify the compounds given in the question. In this case, we have pentane and 2-methylbutane.
Step 3: Check the molecular formula of both compounds. Both pentane and 2-methylbutane have the same molecular formula, C5H12.
Step 4: Analyze the structure of pentane. Pentane has a straight chain of 5 carbon atoms.
Step 5: Analyze the structure of 2-methylbutane. 2-methylbutane has a branched structure with 4 carbon atoms in a chain and 1 carbon atom as a branch.
Step 6: Conclude that since pentane and 2-methylbutane have different arrangements of carbon atoms, they are examples of chain isomerism.
