Calcium carbide is also used in some countries for artificially ripening fruit. When calcium carbide comes in contact with moisture, it produces acetylene gas, which is quite similar in its effects to the natural ripening agent, ethylene. Acetylene acts like ethylene and accelerates the ripening process. Industrial-grade calcium carbide may also contain traces of arsenic and.

Ethylene is a natural ripener, but it is also used as an artificial fruit ripener.
Acetylene is produced when artificial ripening agent calcium carbide comes in contact with moisture.
Acetylene is itself is not used.
Hence answer is ethylene.

Answer: Only D.
The gas used for ARTIFICIAL fruit ripening is Acetylene, not Ethylene.
Ethylene is natural fruit ripening agent.
Calcium carbide produces acetylene when it is in contact with moisture/ water sprayed on it.

Fruit sellers often use calcium carbide in order to increase the rate of ripening. Then wrap a chunk oh CaC2 inside a moist cloth. The reaction between CaC2 and water yields C2H2. So, I thik acetylene is the correct option.

Ethylene is used for artificial ripping of fruit. Acetylene also act as like Ethylene but acetylene is inadvisable because it has carcinogenic properties.

Actually calcium carbide is used as fruit ripening agent which produces acetylene gas (C2H2) This gas behaves same as natural ethelene (C2H4).

For example, bananas are picked when green and artificially ripened after shipment by being gassed with ethylene.

Hi,
Can anyone give me an explanation on what is the biochemical process of artificial fruits ripening?

Acetylene is mainly used for ripening. Acetylene is produced by spraying water on calcium carbide.
