Molecular Polarity
Ethylene is a nonpolar molecule. This is because, unlike a polar molecule, it has an even distribution of electrical charges. No end of the molecule is more negatively or positively charged than another end. Also, there is more than one line of symmetry present which aided me in coming to this conclusion.

C2H4 has the Lewis Structure: The molecular shape is predicted to be trigonal planar around each carbon atom. This is composed of a σ framework and a π-bond.
The valence shell electron pair repulsion model assumes that electron pairs repel one another. Thisproduces a set of molecular geometries which dependonly on the number of valence shell electron pairs and not on the nature of the atoms present. Once again we are concerned only with valence shell electrons and the inner-shell or core electrons play no part in determining the shape of a molecule.
This hydrocarbon has four hydrogen atoms bound to a pair of carbon atoms that are connected by a double bond.
Ethylene serves as a hormone in plants. It acts at trace levels throughout the life of the plant by stimulating or regulating the ripening of fruit, the opening of flowers, and the shedding of leaves.Major industrial reactions of ethene include polymerization and oxidation.Polythene, is the world's most widely used plastic, being primarily used to make films used in packaging, carrier bags and trash liners. Ethylene oxide is also hydrolyzed to produce ethylene glycol, widely used as an automotive antifreeze as well as higher molecular weight glycols.
Solubility: able to dissolve in water
