Draw a segment of polystyrene that contains two head-to-head, two tail-to-tail, and two head-to-tail linkages.
Short Answer
This structure reveals
Two head-to-head linkage given by 1,2 and 3,4 phenyl rings
Two tail-to-tail linkage given by 2,3 and 5,6 phenyl rings
Two tail-to- tail linkage given by 4,5 and 6,7 phenyl rings.
polystyrene that contains two head-to-head, two tail-to-tail, and two head-to-tail linkages.
Step by step solution
Head-to-head, tail-to-tail, head-to-tail addition
Chain growth polymerization exhibits Head-to-head, tail-to-tail, head-to-tail addition. These type of addition can be expressed in an example as follows
Head-to-tail linkage
2.
Head-to-head linkage
3.
Tail-to-tail linkage
Step 2: polystyrene polymer contains two head-to-head, two tail-to-tail, and two head-to-tail linkages.
In this structure two head -to-head linkage are given by 1,2 and 3,4 phenyl rings. Also, 2,3 and 5,6 phenyl rings showing tail-to-tail linkage. Head-to-tail linkage is given by 4,5 and 6,7 phenyl rings.
polystyrene that contains two head-to-head, two tail-to-tail, and two head-to-tail linkages.
Thus, polystyrene polymer contains two head-to-head, two tail-to-tail, and two head-to-tail linkages is drawn above.
