What is accomplished by following the disappearance of the sp2 hybridized peak of the alkene?
It is hard to get the context of the question. The question must be part of a subset of questions and you most likely have a reaction which you are studying. Since the question talks about sp2 hybridized carbon, I will hazard a guess. You are most likely studying a reaction where a sp2 carbon is reduced to sp3 carbon. The disappearance of the peak indicates the completion of the peak. As the reaction proceeds, the peak for the sp2 carbon decreases in intensity while the signal intensity for the sp3 carbon increases. Thus, at any time in the reaction, it may be possible to find out the ratio of the alkene and the product by comparing the signal intensities of the sp2 and sp3 carbon atoms in the starting material and the product.
