Question: What type of isomerism is shown by 1-butanol and 2-butanol?

Options:

Correct Answer: Structural isomerism

Solution:

1-butanol and 2-butanol differ in the position of the hydroxyl group, hence they are structural isomers.

What type of isomerism is shown by 1-butanol and 2-butanol?

What type of isomerism is shown by 1-butanol and 2-butanol?

Step 1: Understand what isomerism means. Isomerism is when two or more compounds have the same molecular formula but different structures.
Step 2: Identify the compounds in the question. We have 1-butanol and 2-butanol.
Step 3: Look at the structure of 1-butanol. It has the hydroxyl group (-OH) on the first carbon.
Step 4: Look at the structure of 2-butanol. It has the hydroxyl group (-OH) on the second carbon.
Step 5: Notice that the only difference between 1-butanol and 2-butanol is the position of the hydroxyl group.
Step 6: Since they differ in structure but have the same molecular formula (C4H10O), they are classified as structural isomers.
