Fuzzwood Posted September 13, 2015 Share Posted September 13, 2015 ... Explain with the H+ dissociation So why don't you give that a try? Link to comment Share on other sites More sharing options...
BabcockHall Posted September 14, 2015 Share Posted September 14, 2015 Start by looking both compounds up in a table of pKa values. Link to comment Share on other sites More sharing options...
Elite Engineer Posted September 16, 2015 Share Posted September 16, 2015 Which dissociates more completely. As BabcockHall said, check the pka values, it should be clear. Link to comment Share on other sites More sharing options...
Rexspidy Posted September 17, 2015 Author Share Posted September 17, 2015 Ya it is clear with pka values but how formic acid can be stabilize more than C6H5COOH after H+ dissociation Link to comment Share on other sites More sharing options...
BabcockHall Posted September 17, 2015 Share Posted September 17, 2015 I might offer a guess that it has something to do with solvation. How could you test that hypothesis? Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted September 18, 2015 Share Posted September 18, 2015 It has to do with stability. You should ask yourself whether the phenyl ring is electron donating or withdrawing in this context. Link to comment Share on other sites More sharing options...
BabcockHall Posted September 19, 2015 Share Posted September 19, 2015 My understanding of Felix Carroll's table of gas-phase acidities (Table 7.4, p. 406) suggests to me that benzoic acid is actually stronger than formic acid in the gas phase.
