Question

You decided to check the purity of your product by TLC. You spotted salicylic acid (lane 1), your crude synthetic aspirin (lane 2) and a sample of pure aspirin (lane 3). After elution, draw a picture of what developed TLC plate (UV visualization) would look like?

Expert Solution

Step 1

TLC Work by polarity of compounds. that means high polarity of a compound then lowest distance travel in TLC Plate and The difference between the two is that aspirin is salicylic acid with the free OH of salicylic acid having been esterified. Both compounds still have the -COOH group. The -OH group is more polar than the ester so salicylic acid is more polar than aspirin.
