Which one of the following is used for ripening of fruits ?

Correct option is B

The correct answer is (b) C₂H₄ (Ethylene)

Ethylene (C₂H₄) is a natural plant hormone that plays a significant role in the ripening of fruits. It accelerates the ripening process by inducing physiological changes in the fruit, such as:

• Conversion of starches to sugars
• Breakdown of chlorophyll, leading to color changes
• Softening of the fruit due to changes in cell wall structure

C₂H₄ in Agriculture:

• Ethylene is used artificially to ripen fruits like bananas, mangoes, and tomatoes in a controlled manner.
• It is preferred over other chemicals because it is naturally produced by plants themselves during the ripening process.

Additional Information:

• C₅H₁₀ (Pentene): A hydrocarbon from the alkene family. It’s primarily used in chemical synthesis and fuel production.
• C₃H₈ (Propane): A hydrocarbon from the alkane family, commonly used as a fuel (e.g., for heating and cooking).
• C₂H₆ (Ethane): A simple alkane hydrocarbon, mainly used as a fuel and a petrochemical feedstock.
