Question

to what extent do covalent compounds conduct electricity?

always
usually
rarely
never

Explanation:

Step1: Understand covalent compounds

Covalent compounds are formed by sharing electrons between atoms.

Step2: Analyze electrical conductivity

In covalent compounds, there are no free - moving ions (in solid or pure liquid state). For electrical conductivity, free - moving charged particles (like ions in ionic compounds or electrons in metals) are required. Covalent compounds in their pure form (not dissolved in a solvent to form ions) do not have these free - moving charged species.

Answer:

never
