Also, circulate the hydrogens to be replaced, and indicate the
type: 3 °, 2 °, 1 ° or benzyl.
Fig. 2. The hydrocarbons in today's experiment. Prelab Preparation Write the balanced equation for the reaction of each hydrocarbon (cyclohexane, methylcyclohexane, toluene, ethylbenzene, isopropylbenzene, and t-butylbenzene) with molecular bromine. Assume that only the most reactive hydrogen will be substituted and that each compound will react only once Use the relative reactivity of the different types...
The experiment of free radical stability.4.0ml of dichloromethane was added to each four 13 *100mm test tubes.to each test tube 1.0ml of a different aromatic hydrocarbon-toluen,ethylbenzene,isopropylbenzene and t-butylbenzene and swirl to mix.under the hood 1.0 M bromine in dichloromethane to each test tube.time was also recorded after addition of bromine,2 minutes,35 seconds. 20 seconds and 14 minutes respectively.1.arrange the four hydrocarbons in order of their reactivity towards bromine,most reactive first and compare with the results.2.write a balanced equation for each...
Synthesis Based Experiment 1: Free Radical Bromination of 1,2-Diphenylethane 1. If the R,R and S,S enantiomers of 1,2-dibromo-1,2-diphenylethane have an observed melting point range of 113 -114'C and the meso 1,2-dibromo-1,2-diphenylethane has an observed melting point range of 236-237 C, which stereoisomer did you isolate? TLC 2. All three of these dibromo stereoisomers were produced in this reaction but you only isolated one of them. Explain this result taking into account the large differences in the three stereoisomers melting point...
How many distinct monochlorinated products can result when 2-methylpropane is subjected to free radical chlorination? A) 1 B) 2 C) 3 D) 4 E) 5 Please explain
2. The addition of HBr to 2-methylpropene can, in principle, give either 1-bromo-2- methylpropane or 2-bromo-2-methylpropane. In reality, only the latter is formed. Show mechanisms for the formation of each of these alkyl bromides, using curved arrows to indicate the flow of electron pairs. Also, construct reaction energy diagrams that describe the energy of the system as a function of the progress in formation of both alkyl bromides. Use these reaction coordinate diagrams to explain why 2-bromo-2-methylpropane is the only...
