Possibly because they have not been picked when immature and artificially ripened with ethylene gas.
If they're out in the open, the fruits release ethylene gas into the air. and since the fruit is exposed to the air, the ethylene gas ruins the fruit. if it is in a plastic container, then the ethylene gas makes the fruit go rotten even faster because the concentration of ethylene is so high in the container.

Oranges are initially green. And in some places they stay greenish yellow. Oranges only turn orange under two circumstances. The first is in colder climates (like the US), where the temperature kills the chlorophyll pigments and carotenoids shows through. Also, oranges in the US are often sprayed with Ethylene Gas, which also kills the chlorophyll and turns them orange. Many greenish yellow oranges taste exactly the same as orange ones, its just that the US consumer demands orange oranges. Whatever floats our boats eh?
No, ethylene is a gaseous hydrocarbon.
Polyethylene oxide and polyethylene glycol are both known polymers. Ethylene oxide and ethylene glycol are, therefore, monomeric.
Ethylene glycol
Ethylene contain hydrogen and carbon.
Ethylene glycol is not of animal origin !
To determine the grams of ethylene needed to react with 0.0126 mole of water, you need to use the balanced chemical equation for the reaction between ethylene and water. Once you have the balanced equation, use the molar ratio between ethylene and water to convert moles of water to moles of ethylene. Then, use the molar mass of ethylene to convert moles of ethylene to grams of ethylene.
