  • How is ethylene produced in fruit?

    Ethylene is a gas and is known as the “fruit-ripening hormone.” Every fruit has a certain level of ethylene production throughout its lifecycle. However, in some fruits, ethylene levels shoot up when the fruit starts ripening. These fruits can also respond to external ethylene by increasing their ripening rate.

    How does ethene work in plants?

    Ethylene is regarded as a multifunctional phytohormone that regulates both growth, and senescence. It promotes or inhibits growth and senescence processes depending on its concentration, timing of application, and the plant species. Ethylene governs the development of leaves, flowers, and fruits.

    How does ethene ripen fruit?

    Most fruits produce a gaseous compound called ethylene that starts the ripening process. When harvested after the rapid rise in ethylene, they quickly soften and senesce in storage. Other varieties have a slower rise in ethylene and slower ripening rate.

    What method is used to prepare ethylene glycol from ethene?

    The method used to prepare ethylene glycol from ethene is hydroxylation.

    How is vicinal glycol prepared from ethene?

    In the industrial preparation of ethylene glycol, ethylene (IUPAC name: ethene) is oxidized to ethylene oxide (IUPAC name: oxirane) using oxygen and a silver catalyst.
