Write a test to differentiate between pentan-2-one and pentan-3-one.

Text Solution

AI Generated Solution

To differentiate between pentan-2-one and pentan-3-one, we can use the iodoform test, which is specifically useful for identifying methyl ketones. Here’s a step-by-step solution: ### Step 1: Understand the Structures - **Pentan-2-one** has the structure: \[ CH_3-CH_2-CO-CH_2-CH_3 \] The ketone group (C=O) is on the second carbon, and it has a methyl group (CH₃) adjacent to the carbonyl carbon. ...
