Julio wrote some facts about covalent compounds in his lab notebook. The picture shows his lab notebook.

Question

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.

Answer 1

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

This statement is incorrect. Covalent compounds typically form bonds between two nonmetals, not between a nonmetal and a metal.
