Please draw the inverted chair forms of the products for the two equilibrium reactions
shown below. Circle the equilibrium reaction that would have a AG = 0, i.e., the relative energy of
the reactant (to the left of the equilibrium arrows) equals the relative energy of the product? [No

Please consider the Newman projection of tartaric acid drawn below as an eclipsed
conformer (1). Please draw the most stable conformer and two intermediate energy conformers
noting that staggered conformers are lower in energy than eclipsed forms even if the staggered
conformers have gauche relationships between groups. [Draw the substituents H and OH on the front
carbons and H, OH and CO₂H on the back carbons based on staggered forms. -CO₂H is larger than -OH.]
