Write the chemical equation that represents the formation of (b) polyacrylonitrile from acrylonitrile (polyacrylonitrile is used in home furnishings, craft yarns, clothing, and many other items).

Video transcript

Hello everyone in this video, We're trying to demonstrate how a chemical reaction that illustrates how surround A. Can be formed from this molecule here. So we're here dealing with a addition politicization. So this is when let's go ahead with this out. So again we're dealing with edition polymer ization. So this means that our double bond essentially sort of opens up and we're also forming a C. C. Single bond with the other molecules. So we have the final I. Dean chloride molecules. Alright, so starting off with this first one here, we can see that we still have this double bond here. So that is incorrect. Any double bond should be sort of opening up. So basically breaking so A. Is incorrect. And then for B. Then everything seems to be scroll down to see this. So for this be possibility we can see that this double bond is not there and our clients are still intact in the appropriate positions. So B is a correct answer. But let's just double check to see if C and D. Are correct or not scrolling down. So for see here, we can see that the chlorine atoms have changes positions and we don't we're not dealing with a member of any sort here. So this is incorrect unless the answer D. Then we can see that we still have a double bond and this leads to break and our chlorine atoms have changed or rearranged its position. So that's also incorrect. So the only correct answer that we have for this problem is going to be answer choice B. And that's going to be my final answer for this problem.
