Q. Why are RCOOH more acidic than PhOH though conjuagste base of latter is more stable?
dipendra you are correct.....
due too precence of H bonding in Rcooh
Actually the correct answer is that in RCOOH the -ve charge resonances on Oxygen atoms which is electronegative element.. thus it is stable bt in phenol it resonances on carbon. Being non electronegative it is unstable
Because of more resonance structure of RCOO- than of phenol hence becomes more stable . Hence acidic
