organic acids

If organic compounds form covalent bond and are insoluble in water , then how organic acid solution conduct electricity like acetic acid?

I'm unsure of the question.

Covalent bonds do not necessarily make a molecule insoluble in water (carbon dioxide for example).

The Polarity (difference in electronegativities) is a major factor in deciding whether or not a substance will dissolve. As oxygen is highly electronegative compared to hydrogen this makes the water molecule polar and since like dissolves like other polar bonds will dissolve in water.

As C=O is polar the C=O bond in acetic acid will cause the molecule to dissolve. A molecule like hexane with only C-H bonds will not dissolve because C-H is not polar. Fats and oils which have one polar end and one non polar end only partially dissolve (which gives a soap effect like in the washing up bowl.)

I'm also pretty sure that any melted/dissolved compound can be made to conduct electricity because there are free electrons to conduct the current

All organic compounds form covalent bond. And those solution conduct electricity that break into ions because these are ions that conduct electricity. So , in acetic acid which is organic compound and form covalent bond do not break into ions to conduct electricity but it does. Why?

All organic compounds form covalent bond. And those solution conduct electricity that break into ions because these are ions that conduct electricity. So , in acetic acid which is organic compound and form covalent bond do not break into ions to conduct electricity but it does. Why?In this case, acetic acid does conduct electricity like every other strong base or acid. Their mixture with water creates ions, which are responsible for the conductibility as you all know.

I think I know what you mean though, because there's a slight nuance to have in mind when talking about acetic acid. PURE acetic acid ionizes completely while common acetic acid partly ionizes, which mean charged particles can still be found and conduct electricity. But you are correct when you say that organic compounds shouldn't usually conduct electricity due to their lack of chemical bonds. But as I stated earlier, their mixture with water is what creates this rare phenomena, sometimes even considered as an exception.

Also, since water conducts electricity, you would need to completely purify any compound you wanted to test experimentally.

organic acids form ions because of the O-H and the OH-C=O structure.
since oxygen is extremely electronegative compared to hydrogen it will attract the electrons of the bound near to himself.That creates a negative pole on the oxygen and a positive one on the hydrogen.The free pair of electrons on the oxygen of water attracts the hydrogen from the organic acid hence breaking the O-H bound.
The OH-C=O structure creates a phenomenon called electronic resonance which intensify the effect of the oxygen "stealing" the hydrogen electron.Thats why alcohols have O-H bounds but don't ionize.
sorry for my poor English.Hope you can understand it.
