Experiment: Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below. Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization. Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C Sample C-Cool the third sample in an ice-bath to 0-2 °C Results: weight after recrystalization and melting point temp.

Interpretation:

For the each given reactions, the products and the mechanism that explains the formation of each product are needed to be determined.

Concept introduction:

Conjugated Dienes undergoes addition reactions with HBr as similar to simple alkenes addition with HBr .

The allylic carbocation is formed as an intermediate by the addition of proton in the HBr .

The Br− (nucleophilic) can attacks in either of the two resonance stabilized carbocation’s in the in the allylic intermediate.

Symmetrical diene like butadiene will produce only two products. Because the intermediates allylic carbocation formed are same.

For the Butadiene derivatives, there are four carbons for addition of proton, but at C1 and C4 carbons only forms the allylic carbocation.

To determine: the products and the mechanism that explains the formation of each product for the given reaction.
