Answer:
Atoms must have similar electronegativities in order to share electrons in a covalent bond.
Explanation:
Covalent bonding is one of the bondings that occurs between the atoms of elements. It is the bonding in which atoms share their valence electrons with one another. However, the ELECTRONEGATIVITY, which is the ability of an atom to be attracted to electrons play a major role in the formation of covalent bonds.
When atoms of different electronegativities combine, the more electronegative atom pulls more electrons towards itself, hence, an IONIC bond is formed. However, when the electronegativities of the atoms are similar, the sharing of their electrons becomes stronger. Hence, ATOMS MUST HAVE SIMILAR ELECTRONEGATIVITIES in order to share electrons in a covalent bond.
Density is not a chemical property. It is a physical property.Electromotive force, Flammability and pH are chemical properties.

The compound that contains a multiple covalent bond in the list is C2H4.
<h3>What is a multiple covalent bond?</h3>
A multiple covalent bond is a double or triple bond. The bonds are known by multiple dashes between atoms that are covalently bonded.
Compounds that contain multiple covalent bonds do not contain the full compliment of hydrogen atoms per carbon atom. Hence, the compound that contains a multiple covalent bond is C2H4.
