I am trying to determine the type of bond(ionic or covalent)based on conductivity.How can I easily understand?

Question

examples:vegetable oil conductivity none
salt water " good
sugar water " none
antacid in water " poor
dishwasher detergent " good
bleach " fair
Carbonated drink " poor
0.1 M HCI " good
0.1 M NaOH " good
Vinegar " fair
Coffee " poor
Ammonia " fair

Answer 1

If it's a good conductor, it is an ionic bond. The ions are carrying the charge on them since they are the ones that have a charge. In ionic bonds, an electron is lost to another element, so the charges are very mobile. Covalent bonds don't really carry charges very well because the electron(s) are being shared by neighboring atoms and so they kinda stick together as apposed to sharing. Hope this helps. :)

Answer 2

in an ionic bond electrons are transferred from one element to other so that both of them become stable charged particles called ions ,
for example in NaCl na loses an electron to form Na+ which has the same electronic configuration as neon and it is very stable since its vavence shell is completely filled. can Cl accepts that electron to form Cl- which is also very stable for the same reason. in solid state these ionic compounds exist as crystals in which each ion is surrounded by 6 or 8 oppositely charged ions. but in liquid state they disassociate into their constituent ions and thus due to the presence of ions which act as charge carriers thus water becomes a good conductor.
but in covalent bonds an electron pair is shared by two atoms and no ions are formed
i hope this will help you

Answer 3

Don't go 4 shortcuts. the best way to understand the type of bondings without confusion is to go 4m the base. First understand the electronic configuration of the element and the arrangement of electrons in the atom,the properties of those elements, & then the electronegativity. while studying the electronegativity, u will be able to know the type of bonding they form. Coz the main application of electronegativity, is to find the nature of bond. ( Hope that I hav given u the right information.)

Answer 4

I answered your question earlier, did it not help at all?

Poor=Covalent
Fair and Good=Ionic
