In the R,S system R,R and S,S are?
enantiomers
What is an achiral compound possessing two or more chiral centers that also has chiral isomers?
meso compound
What RS combos are enantiomers in the R,S system?
R,R and S,S R,S and S,R
When will the molecules be meso compounds according to the R,S system?
Will be the R,S = S,R stereoisomer if both chiral centers have the same 4 groups attached
What is a 2-D representation of a molecule; in these projections, groups on the right and left are by convention in front, while those at the top and bottom are to the rear?
fischer projections
What Will be the R,S = S,R stereoisomer if both chiral centers have the same 4 groups attached?
meso compound
Define Meso compound
an achiral compound possessing two or more chiral centers that also has chiral isomers
Define fischer projections
a 2-D representation of a molecule; in these projections, groups on the right and left are by convention in front, while those at the top and bottom are to the rear
In the R,S system R,R and S,R are?
enantiomers
How does R,S system adjust when H is in front?
• If molecule has H in front –> reverse what you have o Clockwise = S o Counterclockwise = R
What is the relationship between stereoisomers and chiral centers?
• When two or more stereocenters exist in a molecule, multiple stereoisomers are possible for a molecule with n chiral centers, the max number of stereoisomers possible is 2^n
