3) Provide the appropriate chemicals to achieve the conversions shown in the scheme below (26 points). d. b. a. с. h. f. e. k. i. j. m. 4) Radicals in some instances can lead to undesired reactions. Foods are known to contain radical inhibitors, known as preservatives or antioxidants. These species act by preventing radical chain reactions that can lead to degradation of packaged foods. One synthetic preservative used commonly in both the food industry and the chemical industry is BHT (butylated hydroxytoluene), shown below. Using your knowledge of radical chain mechanisms, draw the propagation steps for the reaction of BHT with an alkyl radical (R-) (9 points). BHT ம்
