Explanation / Answer

Aspirin synthesis

Q1.

Part 1: the results showed carboxylic acid did not remain intact during synthesis. No bubbles ae seen here, whereas, in aspirin (last column) we got bubbles formed by reaction of free acid group - No

Part 2 : No the results showed absence of acid functionality, which is same as before recrystallization. The carboxylic acid group did not remain intact- No

Q2.

Part 1 : The salicylic acid was not detected in crude aspirin sample - No

Part 2 : Did you detect salicylic acid in recrystallized sample - Yes

Part 3 : Did recrytsallization reduce amount of salicylic acid in sample - No

Part 4 : Did you detect salicylic acid in commercial aspirin sample - Yes

Part 5 : The recrystallized sample had less amount of salicylic acid as compared to commercial aspirin sample. The sample having greatest amount of salicylic acid is,

Commercial sample
