Concept Introduction:
Acid Catalysed addition of water: When water is added to alkyne in the presence of an acid, the product formed will be an enol. Enol contains a double bond and a
If a carbonyl group is bonded to two alkyl groups, it is called as a ketone. The enol formed in the acid catalysed addition of water will be easily converted into a ketone.

- Hydration of aldehydes and ketones can be catalyzed by acid or base. Bases catalyze hydration by: protonating the carbonyl oxygen making the carbonyl group more electrophilic employing hydroxide ion, which is a better nucleophile than water making the carbonyl group less electrophilic shifting the equilibrium position of the reaction to favor productsarrow_forwardWhat ketones are prepared by the following reactions?arrow_forwardreaction of ketones with phosphorus halidesarrow_forward

O O H+ OH H+ benzyl isobutanoate H₂Oarrow_forwardEthyl butyrate, CH3CH2CH2CO2CH2CH3CH3CH2CH2CO2CH2CH3, is an artificial fruit flavor commonly used in the food industry for such flavors as orange and pineapple. Its fragrance and taste are often associated with fresh orange juice, and thus it is most commonly used as orange flavoring. It can be produced by the reaction of butanoic acid with ethanol in the presence of an acid catalyst (H+H+): CH3CH2CH2CO2H(l)+CH2CH3OH(l)H+⟶CH3CH2CH2CO2CH2CH3(l)+H2O(l)CH3CH2CH2CO2H(l)+CH2CH3OH(l)⟶H+CH3CH2CH2CO2CH2CH3(l)+H2O(l) A chemist ran the reaction and obtained 5.40 g of ethyl butyrate. What was the percent yield, The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0% yield. How many grams would be produced from 7.45g of butanoic acid and excess ethanol?arrow_forward
