A) Duprene
B) Natural rubber
C) Buna-S
D) Buna-N
Correct Answer: A
Solution :
Idea This problem contains conceptual mixing of molecular structure determination and polymerisation of identified monomer. To solve this problem students are advised to follow following steps. ? Calculate the value of degree of unsaturation. ? Draw the possible structures. ? Choose the correct structure among all possible structures. ? Then, complete chemical reaction according to given information. Determination of molecular structure of\[{{C}_{4}}{{H}_{5}}Cl\] Degree of unsaturation\[=(4+1)-\frac{6}{2}=5-3=2\] Since this molecule does not contain any ring or tripple bond. hence it must be a diene.You need to login to perform this action.
