Students have asked these similar questions

piperidine undergoes the series of reactions shown here, 1,4-pentadiene is obtained as the product. When the four different methyl-substitutedpiperidines undergo the same series of reactions, each forms a different diene: 1,5-hexadiene; 1,4-pentadiene; 2-methyl-1,4-pentadiene; and3-methyl-1,4-pentadiene. Which methyl-substituted piperidine forms which diene?

The rate law for addition of Br2 to an alkene is first orderin Br2 and first order in the alkene. Does this informationsuggest that the mechanism of addition of Br2 to analkene proceeds in the same manner as for addition of HBr?Explain.
