Covalent compounds never conduct electricity well. This implies the correct answer is D.
Covalent compounds never conduct electricity because they are formed by the sharing of electrons. Covalent compounds do not dissociate and don’t generate charge ions in solution and since they are electrically neutral, they cannot conduct electricity.
Further Explanation
Covalent compounds can be defined as molecules that are formed by covalent bonds whereby its atom (nonmetal) share one or more pairs of valence electrons. In other words, a covalent compound is the sharing of electrons between two or more atoms. These bonds mostly occur between two or more nonmetal atoms.
Nonmetal refers to an element that doesn’t possess metallic characteristics, they are gases at room temperature and do not conduct electricity or heat. They can be found towards the far right on the periodic table.
some of the physical and chemical properties of covalent compounds include:
Most of the covalent compounds have low melting and boiling point
Covalent compounds don’t conduct electricity because they are electrically neutral
Solid covalent compound possess soft structures similar to graphite
They are also bad conductors of heat.
Some covalent compounds are soluble in water
Covalent compounds are also soluble in organic solvent
Therefore, covalent compounds never conduct electricity well.
