Ethylene is a ________ molecule. A. Polar B. Ionic C. Covalent D. Nonpolar

Ethylene is a nonpolar molecule.

A polar molecule is a molecule in which the electrons are shared unequally between the atoms. This results in a partial positive charge on one atom and a partial negative charge on the other atom.

An ionic molecule is a molecule in which one atom has donated an electron to another atom. This results in a positive ion and a negative ion.

A covalent molecule is a molecule in which the atoms share electrons equally.

In ethylene, the two carbon atoms are bonded to each other by a covalent bond. The two carbon atoms also share electrons with the four hydrogen atoms. The electrons are shared equally between the carbon and hydrogen atoms, so ethylene is a nonpolar molecule.
