: Draw the structures of R-benzoin, S-benzoin, R, R-hydrobenzion, S, S-hydrobenzion and R, S-hydrobenzion (meso-hydrobenzoin) with the correct stereochemistry. Also, determine the molecular weights of benzil and the possible products.

don't know

Explanation:

I just don't know

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
