julio wrote some facts about covalent compounds in his lab notebook. the picture shows his lab notebook.

covalent compounds:
-bonds between nonmetals
-have low melting and boiling points
-dissociate into ions in an aqueous solution
-have weaker bonds than ionic compounds

julio made a mistake in his list. which statement best describes the mistake he made?

a
covalent compounds do not have bonds between nonmetals; they are between a nonmetal and a metal.

b
covalent compounds do not have low melting and boiling points; they have high melting and boiling points.

c
covalent compounds do not dissociate into ions in an aqueous solution; they are not conductive in an aqueous solution.

d
covalent compounds do not have weaker bonds than ionic compounds; they have stronger bonds than ionic compounds.
