Question

Which element can combine with chlorine to make the best conductor of electricity when in the liquid form?
A) C because it has a slightly lower electronegativity value
B) Cl because it has the same electronegativity value
C) Li because it has a much lower electronegativity value
D) F because it has a slightly higher electronegativity value
please tell me, and why

Answer 1

Ionic substances form giant ionic lattices containing oppositely charged ions. They have high melting and boiling points, and conduct electricity when melted or dissolved in water. Li does have a low electronegativity value.
The element that should combine with chlorine has to be polar or else it wont conduct electricity because - Substances with a simple molecular structure do not conduct electricity. This is because they do not have any free electrons or an overall electric charge. F-Cl is polar due to net dipole moment but still ionic compound when dissolved are better conductor of electricity so i would go with lithium
