Would you expect Hydrogen Fluoride to conduct electricity?? please explain your answer..?

Question

it's actually 1 of my homework..
and you know??
my chemical is bad..
so, please help me answer this question..
thanks..

Answer 1

If you mean HF gas, no I would not...H is the strongest reducing agent and F the strongest oxidizing...together they hold their shared electrons too tightly to let any roam around offering electronic conduction.
But if you mean HF in aqueous soln, yes...it ionizes: HF + H2O<-->H3O+ + F-...giving ionic conduction.

Answer 2

No.
Hydrogen fluoride itself would not conduct electricity. The bond between hydrogen and fluorine is covalent and although it's polar, there are actually not many ions. The reason for that is hydrogen fluoride is in gasseous state.
On the other hand if you dissolve HF in water you get hydroflouric acid. Which is not really strong acid but it produces more than enough free ions (H+ and F-) that solution is well conducting.

Also ionic compounds do not conduct if they are in solid state. They only conduct if they're melt or dissolved. The point of conductivity is that you have to have free charged particles (ions in solutions, free electrons in metals)

Hope this will help.

Answer 3

well yes it would because it is a polar covalent compound
Explanation of a polar covalent compound:
POLAR BONDING results when two different non-metals unequally share electrons between them. One well known exception to the identical atom rule is the combination of carbon and hydrogen in all organic compounds.

The non-metal closer to fluorine in the Periodic Table has a greater tendency to keep its own electron and also draw away the other atom's electron. It is NOT completely successful. As a result only partial charges are established. One atom becomes partially positive since it has lost control of its electron some of the time. The other atom becomes partially negative since it gains electron some of the time.
hope i helped!! all the best with your homework!

Answer 4

You would expect it to conduct electricity, but in fact it does not because it forms the covalent compound H2F2. To electrolyse hydrofluoric acid a mixture of the acid and KG are used.

Answer 5

By absolute coincedence, the wording of your question is exactly that which starts the 1983 book 'My Aunt the Camel' by Pantos Ingoselio. What is weird was that he came from Mexico too.

Answer 6

I would, as the two elements are on different sides of the periodic table, hence, their electronegitivity is much different, allowing for the molecule to be polar.
