Ompound a (c6h6) undergoes catalytic hydrogenation over lindlar catalyst to give a compound b which in turn undergoes ozonolysis followed by workup with aqueous h2o2 to yield succinic acid and two equivalents of formic acid. in the absence of a catalyst poison hydrogenation of a gives hexane. propose a structure for compound a.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
