Question

What stereoisomers are obtained from each of the following reactions?

Short answer

Here we have to draw the stereoisomers of the following reactions:

a)

b)

c)

d)

Step-by-step solution

What is stereoisomer-

Two or more compounds which differ in the spatial arrangement of their atoms are called as stereoisomers i.e the molecules which are stereoisomers of each other are made from same atoms, connected in the same sequence but the atoms are arranged differently in space.

Final answer

a) In this reaction markoniv’s rule will apply i.e hydrogen will go to that double bonded carbon which has more no of hydrogens attached and chlorine will go towards that carbon which has less number of hydrogens attached.

b) In this reaction markoniv’s rule will apply i.e hydrogen will go to that double bonded carbon which has more no of hydrogens attached and OH will go towards that carbon which has less number of hydrogens attached. As this is symmetrical alkene so both the ions can go towards any carbon.

c) In this reaction markoniv’s rule will apply i.e CH₃will go to that double bonded carbon which has more no of hydrogens attached and OH will go towards that carbon which has less number of hydrogens attached.

d) In this reaction markoniv’s rule will apply i.e hydrogen will go to that double bonded carbon which has more no of hydrogens attached and bromine will go towards that carbon which has less number of hydrogens attached.
