Which of the following is a syndiotactic polymer in −[−CH2−C(YZ)−]n−
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
C
The Y and Z groups are arranged in a random fashion
D
Y and Z groups are same
Answer
The Y and Z groups lie alternately on each side of the chain
Explanation
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.
