Isomers
A molecule that has a mirror image but cannot be placed on top of it perfectly is termed...
What is a chiral object?
Another term for cis-trans isomers...
What is geometric isomers?
This angle of rotation is allowed without changing the stereochemistry for Fischer Projections:
What is 180 degrees?
The label "R" for an asymmetric carbon atom indicates this direction:
What is right; clockwise.
Which direction would (R)-alanine rotate plane-polarized light?
What is we cannot predict which direction a particular enantiomer (either R or S) will rotate the plane polarized light.
The difference between constitutional isomers and stereoisomers...
What is constitutional isomers differ in their bonding sequence (their atoms are connected differently); stereoisomers have the same bonding sequence, but differ in their orientation in space.
Cis-1,2-difluorocyclopentane chiral...
What is no?
This would cause the R/S configuration of a Fischer projection to flip:
What is if the 4th priority group was on a horizontal.
This term describes the structural relationship between (2R,3R,4S)-2,3,4-trichloroheptane and (2S,3S,5R)-2,3,5-trichloroheptane: (Options: not isomers, constitutional isomers, enantiomers, diastereomers, conformers)
What is constitutional isomers.
Predict the product(s) of the following reaction. CH3CH2O-Na+ + CH3Br --> ????
What is CH3CH2OCH3 + NaBr
Cis-1,2-dichlorocyclopentane chirality...
What is no; it has an internal plane of symmetry and is therefore achiral.
True or false: Cis and trans isomers can interconvert between configurations...
What is false?
Draw the Fischer projections for (2S, 3S)-2-fluoro-3-iodobutane and (2R, 3S)-2-fluoro-3-iodobutane. The structural relationship between these two compounds is:
What is see the board for structure; diastereomers.
Draw the structure of (2R,3R)-2,3-dibromo-3-chloropentane using a line structure. Stereochemistry must be shown clearly.
What is see the board :)
The term for compounds that rotate plane polarized light toward the right and the left:
What is optically-active isomers
True or False: All stereo centers are chiral centers.
What is false?
Chiral centers of 2,3-dimethylpent-4-ene...
What is 1?
Draw the Fischer projections for (2S, 3R) 2-bromo-3-chlorobutane and (2R, 3S) 2-bromo-3-chlorobutane. What is the relationship between these compounds?
What is see the board for structures; enantiomers.
Which would have the higher melting point: (R)-2-bromobutane or (S)-2-bromobutane?
What is they would be expected to be nearly identical?
A racemic mixture is defined as:
What is a solution of equal amounts of two enantiomers so that the mixture is optically inactive?
Draw the structure of a meso form of 1,3-dichlorocyclopentane. Take particular care to indicate three-dimensional stereochemical detail properly.
What is see board!!!!!!!
This type of stereoisomers would be possible to separate via distillation? Explain briefly.
What is diastereomers; they would have different boiling points because they don't have the same physical properties because they aren't mirror image molecules.
Draw the Fischer projection of (S)-2-hydroxybutanoic acid, CH3CH2CH(OH)COOH.
What is see the board!
Draw the enantiomers of 1,3-dibromobutane and label them R and S.
What is see the board!
A compound has 6 asymmetric carbon atoms so the maximum amount of stereoisomers it could have is...
What is 64?
