(b)
To determine: The ratio of reactants (cyclohexane and chlorine) that would be used for the synthesis of chlorocyclohexane.
Interpretation: The ratio of reactants (Cyclohexane and chlorine) that would be used for the synthesis of chlorocyclohexane is to be predicted.
Concept introduction: The chemical reaction which proceeds through the formation of radicals is known as chain reaction. It involves three steps, initiation, propagation and termination. The initiation step occurs in the presence of light. The quantum yield of chain reactions is very high.

- Show all steps and reagents needed to convert cyclohexane into each compound: (a) the two enantiomers of trans-1,2- dibromocyclohexane; and (b) 1,2-epoxycyclohexane.arrow_forwardWhich of the following is most soluble in basic medium? a. cyclopropane b. 1,3-cyclobutadiene c. 1,3-cyclopentadiene d. benzenearrow_forwardShow the structure of the product from the Diels-Alder reaction between 2 moles of isoprene (2-methyl-1,3-butadiene) and one mole of quinone.arrow_forward
- A saturated hydrocarbon burns in oxygen to give carbon dioxide and water. Approximately twice as much CO2 as H2O (by weight) is produced by this combustion, the actual factor being 2.03. Light induced chlorination of the hydrocarbon by 2.0 equivalents of chlorine gives a mixture of mono-, di- and trichloro compounds, along with small amounts of higher chlorination products. Only one monochloro isomer is formed, but there are two dichloro isomers and three trichloro isomers produced in the reaction. Based on this information, you should be able to identify the hydrocarbon, and draw structural formulas for the chlorinated compounds.arrow_forwardSolution:- 3. Determine the amount, in of a (2.20 M s olution of dichloromethane needed to completely react with 15.72g cyclohexene to give 1,2-dibromocuclohexanw. Assume 12% excess is needed in order to react completely. a . How much 1,2 -dibromocyclohexane would theoretically be produced ? c.

- Comment on the difference between the enthalpy of combustion values of anthracene, napthalene, and phenathrene. delta H anthracene = -7063.8±5.3 kJ/mol delta H napthalene = -5160. ± 20. kJ/mol delta H phenanthrene is -7040. ± 30. kJ/molarrow_forwardA benzene ring alters the reactivity of a neighboring group in the so-called “benzylic” position, similarly to how a double bond alters the reactivity of groups in the “allylic” position. Benzylic cations, anions, and radicals are all more stable than simple alkyl intermediates. a) Use resonance structures to show the delocalization of the positive charge, negative charge, and unpaired electron of the benzyl cation, anion, and radical.arrow_forwardDehydrohalogenation of 1-chloro-1-methylcyclopropane affords two alkenes (A and B) as products. Explain why A is the major product despite the fact that it contains the less substituted double bond.arrow_forward
