Answer #1

If both stereocenters are mirror image of each other then they should be called as Enantiomers.

(2R, 3R) and (2S, 3S) isomers are called enantiomers.

If two stereoisomers are not super imposable then they will be called as diastereomers.

(2S, 3S) and (2S, 3R) - are diastereomers

(2R, 3R) and ( 2S, 3R) - are also diastereomers

SIn same molecule if half of the molecule is mirror image of other half molecule then they will be called as meso compound.

(2R, 3S) isomer is meso compound.

Molecular set #4: Construct the compound cyclopropane (C3H6). Draw the 3D model. State the shape of the molecule. State the probable bond angles Compare these angles to the normal bond angles for alkanes. State a conclusion about possible strain in the molecule. Now replace two hydrogens, one each on adjacent carbon atoms, with chlorines. This creates dichlorocyclopropane, C3H4Cl2. Move one chlorine atom so that you have built both the cis and the trans isomers of this compound. These are called...
