No, ethene (C2H4) is a nonpolar molecule because it has a symmetrical structure with the same electronegativity of carbon and hydrogen atoms. This means that the distribution of electrons is equal throughout the molecule, resulting in no overall dipole moment. **

Ethene is an unsaturated hydrocarbon. It contains a double bond between the two carbon atoms, which means it has the capacity to undergo addition reactions. This double bond allows ethene to form new bonds with other atoms or molecules, making it unsaturated. **

Ethene is a nonpolar substance because it consists of two carbon atoms bonded together by a double bond, with each carbon atom sharing four electrons with the other. This symmetrical arrangement of atoms and electrons results in a molecule that has a linear shape and equal distribution of charge, making it nonpolar. Additionally, the electronegativity of carbon is similar, so there are no significant differences in electronegativity to create a dipole moment in the molecule. **

Yes, ethene and ethylene are the same compound. Ethene is the IUPAC name for the compound with the chemical formula C2H4, while ethylene is the common name for the same compound. Both terms are used interchangeably to refer to the colorless, flammable gas that is widely used in the production of plastics and as a plant hormone. **

No, fire-breathing dragons would not be biologically possible. The ability to breathe fire would require a biological mechanism to produce and expel a flammable substance, as well as a way to ignite it. There are no known biological systems that could accomplish this, and the energy required to produce and expel fire would be impractical for a living organism. Additionally, the heat and pressure from breathing fire would likely be harmful to the dragon's own body. Therefore, fire-breathing dragons are purely a product of mythology and fiction. **

Ethene reacts with bromine water by undergoing an addition reaction. The double bond in ethene breaks, and each carbon atom forms a new bond with a bromine atom. This results in the decolorization of the bromine water, changing it from orange to colorless. This reaction is a characteristic test for unsaturation in organic compounds. **

Ethene and ethane are both hydrocarbons, meaning they are composed of carbon and hydrogen atoms. They are both aliphatic compounds, which means they have straight chain structures. Additionally, both ethene and ethane are colorless and odorless gases at room temperature and pressure. **

Propane is a saturated hydrocarbon with the chemical formula C3H8, meaning it contains only single covalent bonds between carbon atoms. Its structure consists of a straight chain of three carbon atoms, with each carbon atom bonded to three hydrogen atoms. Ethene, on the other hand, is an unsaturated hydrocarbon with the chemical formula C2H4, containing a double covalent bond between the two carbon atoms. Its structure consists of two carbon atoms bonded to each other with two hydrogen atoms attached to each carbon atom. Therefore, propane has a linear structure, while ethene has a planar structure due to the presence of the double bond. **
