Options:
A) All Y groups lie on one side of the chain and all Z groups on the other side
B) The Y and Z groups lie alternately on each side of the chain

Show Answer
Answer:
Correct Answer: B
Solution:
There are 3 stereo chemical arrangements are possible (i) Isotactic (Same order):- Here groups are arranged on one side of the chain. All Y groups lie on one side and all Z groups on the opposite side of the chain. (ii) Syndiotactic (Alternating order) - The Y and Z groups lie alternately on each side of the chain. (iii) Atactic (Random order) - The Y and Z groups are arranged in a random fashion.
