Which one of the following organic compounds has fruity smell? A. Alcohol B. Aldehyde C. Ester D. Ether

The correct answer is C. Ester.

Alcohols have a characteristic “alcoholic” smell, which is often described as being sweet or sharp. Aldehydes have a strong, unpleasant, or even sickening smell. Ethers have a sweet, ethereal smell. Esters have a pleasant, fruity smell.

Esters are organic compounds that are formed by the reaction of an acid and an alcohol. The general formula for an ester is R-COO-R’, where R and R’ are alkyl groups. Esters are found in many fruits and vegetables, and they are responsible for the characteristic flavors of many foods. They are also used in perfumes and other fragrances.

Here are some examples of esters:

• Ethyl acetate, which is found in apples and bananas.
• Butyl acetate, which is found in pineapples and apricots.
• Isoamyl acetate, which is found in raspberries and strawberries.
• Vanillin, which is found in vanilla beans.
