Concept introduction:
An alkyne can be converted into aldehyde and ketone by hydration reaction. In hydration reaction, mercuric ion with a dilute acid is used to carry out the reaction. Mercuric ion is used as a catalyst. After the protonation of the alkynyl carbon, the water attacks as the nucleophile and an enol is formed. Enol is unstable and converts into a stable aldehyde or ketone.
(c)
Interpretation:
The explanation of the statement, “The hydration of alkyne is not a reasonable preparative method for cyclohexanone ” is to be stated.

- 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.
