Draw the structures of R-benzoin, S-benzoin, R,R-hydrobenzion, S,S-hydrobenzion and R,S-hydrobenzion (meso-hydrobenzion) with the correct stereochemistry. Also, determine the molecular weights of benzil and the possible products.
Draw the structures of R-benzoin, S-benzoin, R,R-hydrobenzion, S,S-hydrobenzion and R,S-hydrobenzion (meso-hydrobenzion) with the correct stereochemistry. Also,...
Assign R or S stereochemistry to the chirality centers in these Newman structures. Determine if these molecules are chiral. achiral. or meso compound
Draw the structures of the expected organic product(s) formed in the following reactions including correct stereochemistry. If more than one product is possible draw all products and write major or minor product where necessary. Indicate what the mechanism of the reaction is. Assume all reagents listed are present in excess unless otherwise noted. If no reaction occurs, state 'No Reaction'. DMF = dimethyl if ormamide, CH_3 CN = acetonitrile
For each addition route of the reaction, draw the structures of the possible products, including stereochemistry.
For each addition route of the reaction, draw the structures of
the possible products, including stereochemistry. Note that more
than one product is produced in each case since stereochemistry
must be considered.
1. Draw the structure of n-pentane and all of its constitutional isomers. 2. Draw (showing stereochemistry) the meso isomer of 2,3-dibromobutane. 3. Draw two examples of cis-trans isomers with the molecular formula C6H12, one pair containing a double bond and pair containing a ring. (Four structures in total)
can you show the correct R/S stereochemistry with priorities
for all structures as well as E/Z where it is possible.
