which one is more acidic?ethane or benzene?

Answer 1

I'll have to say benzene since the pKa of ethane is around 50 whereas the pKa of benzene is around 35.

Answer 2

Good question.
I see where you are coming from on this one. Since both Ethane and Benzene have 6 Hydrogen atoms in their structure, you want to see which one has the lower pH.
Since Double bonds are stronger than single bonds, Benzene will be less likely to break apart than ethane when dissolved in water (You'll have to add both chemicals to water so the pH can be measured) But, some of the benzene compounds in the solution will give off HC=CH, C=CH and varied carbon radical chains up to 5 carbons in length. These will join with OH, O2 , O and H radicals from the water to form several new derivatives. Ethane will not form as many different derivative chemicals as Benzene but it will form a greater amount because the double bonds in Benzene are stronger and less likely to break.
Most of the derivative chemicals formed will be aldehydes, ketones, alcohols and acids for the benzene.
Most of the derivative chemicals formed will be aldehydes, ketones and alcohols for the ethane.. very little if any acid.
With this said, you'll find that the Benzene / water mixture will have a lower pH.
Good Luck!

Answer 3

Benzene. Ethene is an alkene hydrocarbon, which means amoung other things that it is non-polar and rather unreactive as far as acid-base reactions go.

Answer 4

I'm guessing benzene b/c they use it as a chemical solvent.

Answer 5

benzene

Answer 6

Neither shows any noticeable traces of acidity: in each, all the protons are strongly bound.

Answer 7

benzene.

Answer 8

Neither are acids
