Chemistry 2010 JAMB Past Questions - Question 44: Which of the following is used to hasten the ripening of fruits?

Correct Answer

A

Explanation

Out of the listed options, the compound used to hasten the ripening of fruits is **ethene (C?H?)**, also known as ethylene. Here's why:

* **Ethylene:** This gas is a naturally occurring plant hormone involved in various physiological processes, including fruit ripening. Applying ethylene artificially can accelerate the ripening process, enhancing color, texture, and aroma development in fruits.
* **Ethanol:** While this alcohol has some antimicrobial properties and can potentially impact fruit preservation, it doesn't directly promote ripening like ethylene.
* **Ethyne:** This compound, also known as acetylene, has different chemical properties and applications compared to ethylene and is not used for fruit ripening.
* **Ethane:** This hydrocarbon gas lacks the specific biological activity needed to influence fruit ripening processes.

Therefore, considering the natural role of ethylene as a plant hormone and its ability to stimulate ripening, it stands out as the correct choice among the options you provided.
