- Alkyl halides can be reduced to alkanes by a radical reaction with tributyltin hydride, (C4H9)3SnH, in the presence of light (hv). Propose a radical chain mechanism by which the reaction might occur. The initiation step is the light-induced homolytic cleavage of the Sn-H bond to yield a tributyltin radical.Following is a balanced equation for the allylic bromination of propene. CH2==CHCH3 + Br2 h CH2==CHCH2Br + HBr (a) Calculate the heat of reaction, H 0, for this conversion. (b) Propose a pair of chain propagation steps and show that they add up to the observed stoichiometry. (c) Calculate the H 0 for each chain propagation step and show that they add up to the observed H 0 for the overall reaction.Does the data provide evidence for the claim that the reaction of Br2 with alkenes proceeds via anti‐addition? The mleting point of the product was found to be 234.5-235.5C chemical reaction: trans-stilbene+pyrimindine tribromide --->acetic acid 1,2-di bromo-1,2-diphenylethane
- Chemical Reactions and Mechanisms: Use the space below for reactions and mechanisms. Initiation Propagation Termination (3) Toluene 1° Benzylic2-chloropropane is a major product of the reaction of chlorine with propane under ultraviolet light. Write the mechanism for this reaction including the initiation step and the two propagation steps.4. The following reaction scheme shows the radical polymerization of styrene to make polystyrene. a) Add electron-pushing arrows to show the mechanisms of steps 1-3. Determine if these are initiation, propagation, or termination steps. b) Radical polymerization is often performed in the absence of O2 because the oxygen radical can couple with the polymer radical to terminate polymerization. Propose electron-pushing arrows for step 4 and predict the product of that step.
- Free radical halogenation is used to replace one or more hydrogens on an alkane with one or more halogens (either chlorine or bromine). It is a substitution reaction. A student performs a free radical bromination on 3-methyl-pentane (5.88 g) to create the desired product of 3-bromo-3-methyl-pentane. The product mix, which hopefully contains almost all 3-bromo-3-methyl-pentane, is cleaned up by passing it through a gas chromoatograph, which separates out the 3-bromo-3-methyl-pentane from any undesired products made during the reaction (undesired products are created frequently in free radical halogenation). The initial product mix weighed 9.45 g; the purified 3-bromo-3-methyl-pentane weighed 7.21 g. What is the student's percent recovery?Propose a mechanism for the free-radical chlorination of ethane,CH3¬CH3 + Cl2 ¡hv CH3¬CH2Cl + HClPredict the major products formed when 2- methyl-1-butene reacts with: HCl.
