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.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

that's what i got you can count the number of atoms
