An optically activated alkyne A(C10H14)can be catalytically hydrogenated to butylcyclohexane. Treatment of A with C2H5MgBr liberates no gas. Catalytic Hydrogenation of A over Pd/C in the presence of quinoline poison and treatment of the product B with O3 and then H2O2 gives an optically activated tricarboxylic acid C8H12O6. (A tricarboxylic acid is a compound with three -CO2H groups.) Give the structure of A (without stereoismetry).
