5.41 Discuss whether each of the following compounds can exist in stereoisomeric forms (a) CCH-c-o-CHa; (b) CH2-c-c CHa; ao "c"c"coz stereoisomers can be subdivided into two general categories. are stereoisomers whose molecules are nonsuperposable mirror images of each other. All other stereoisomers are The presence of a single chirality center in a molecule guarantees that the molecule is forms are possible. The ultimate way to test for molecular chiralty is to construct models of the molecule and its image. If the two models are superposable, the molecule that they otherwise the molecules that they represent are A molecule will not be chiral ir it possesses a of symmetry. In case of an odd number of cumulated bonds n bonds and substituents lie in one plane, therefore the end of these molecules sare chiral. That substituents at the ends Mein one plane also means that butatrienes show cis trans isomerism with substituents. Choose molecules that show cs trans isomerism (a) CICH c c CHCI (b) CH2-C C CHO No one of the above molecules show cis-trans isomerism. I czooo 201zuohn wulea sons unc. A Rights Reserved.
