(b)
To determine: The mechanism for the given silver-promoted rearrangement.
Interpretation: The mechanism for the given silver-promoted rearrangement is to be stated.
Concept introduction: The structural changes in carbocations are known as rearrangements. It leads to the formation of more stable ions. Addition of silver nitrate to an alkyl halide in a good ionizing solvent results in the removal of silver ion. This leads to the formation of a carbocation.

- For the gas phase isomerization of cis-1,2-diphenylethene, cis-C6H5 CH=CHC6H5 → trans-C6H5 CH=CHC6H5 the rate constant at 569 K is 2.11 × 10-4 s¯¹ and the rate constant at 608 K is 2.39 × 10 -3 S The activation energy for the gas phase isomerization of cis-1,2-diphenylethene is | s-¹. S kJ.arrow_forward. Provide a synthetic pathway for each of the following multi-step reactions. Do not write any step wise mechanisms. CN HO Br OH SH „Brarrow_forwardThe reaction of the alkene, ethylene, with H2 produces ethane as a product. However, the reaction is incredibly slow in the absence of a catalyst, such as platinum metal. What is the role of the catalyst in speeding up the reaction? Raising the activation energy by breaking the bonds of hydrogen molecules. By bringing together the hydrogen atoms and alkene on the same metal surface, thereby lowering the activation energy. By decreasing the number of reactive inermediates. By increasing the equilibrium constant for the reaction.arrow_forward
- What type of bond cleavage takes place in/what type of intermediate is produced in the following reaction? COH2 H,0arrow_forwardPleasearrow_forward17. In the free energy diagram of a reversible reaction for the formation of B from A, the activation free energy change for the formation of B from A (AG*) is +6 kcal mol-¹ in an uncatalysed reaction and +2 kcal mol-¹ in a catalysed reaction, and that for the formation of A from B (AG,*) is +12 kcal mol-¹ in the uncatalysed reaction. What is the activation free energy change (AG,¹) for the conversion of B to A in the catalyzed reaction? a. Can't be calculated from the information provided. b. + 6 kcal mol-¹ c. + 4 kcal mol-¹ d. +8 kcal mol-¹arrow_forward
- TRUE or FALSE: For a transition state to be considered as the rate- determining step (rds) in a multi-step reaction, it must have the highest change in enthalpy.arrow_forwardWhich reaction intermediate is formed when the following reaction is run in CCl4 as a solvent? Br + Br₂ Br Brarrow_forwardDraw a structural formula for the intermediate in the following reaction: ● ● + Br₂ CH₂Cl2 You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. Do not include counter-ions, e.g., Na+, I, in your answer.arrow_forward
