Two types of transition states are likely to occur in this shift such as chair-like and boat-like transition states. According to the Frontier-Molecular-Orbital theory, both the transition states are allowed transition states inspite of the stability difference. The product obtained from the chair-like transition state has trans-conformation whereas the product obtained from the boat-like transition state has cis-conformation.

- Consider a hypothetical chemical reaction between compound A and compound B, which produces compound C as the final product. The reaction is known to be exothermic and spontaneous. However, when the reaction is carried out under certain conditions, it fails to occur. Explain this observation and propose a potential solution to overcome this hurdle.arrow_forward7.

Give mechanistic explanation and the product formed. (b) Predict the product(s) will be formed from the following reactions: (i) Bromination of p-methylbenzoic acid (ii) Sulphonation of m-bromoanisole (iii) Friedel-craft acylation of o-bromonitrobenzenearrow_forwardThe first observation that this reaction is not a typical ligand substitution was the dependence on the pKb of the incoming ligand (using alkoxides) on the rate of substitution. It has been hypothesized that this is a base-hydrolysis mechanism. The key steps are shown below. [CoCl(NH3)5]2+ + OH– → [CoCl(NH2)(NH3)4]+ (1) [CoCl(NH2)(NH3)4]+ → [Co(NH2)(NH3)4]2+ + Cl– (2) [Co(NH2)(NH3)4]2+ + H2O → [Co(OH)(NH3)5]2+ + NH3 (3) (2) Our standard rate laws for associative and dissociative ligand substitution are rate = k[ML6][L’] and rate = k[ML6], respectively. Derive a rate law for the base-hydrolysis ligand substitution above where equation 1 is the rate determining step.arrow_forward

During an experiment involving conjugated dienes, some doubts arose when discussing the results obtained so far: (a) A student obtained two products from the reaction of 1,3-cyclohexadiene with Br2. His lab partner was surprised to get only one product from the reaction of 1,3 - cyclohexadiene with HBr. Explain these distinct results. (b) One student, seeing the discussion of colleagues, commented that she obtained two distinct products when reacting 1,3,5-hexatriene with HBr, with different yields just by changing the reaction temperature. Explain the results she obtained using reaction mechanism and based on kinetic and thermodynamic control involving conjugated dienes.arrow_forwardb) Optical isomers can often be formed during these reactions. For products A-H indicate how many different optical isomers you expect to form for each from these reactions (you do not have to indicate whether they are diastereomers/enantiomers). c) In the preparation of substance D by ozonolysis, the second step is necessary treatment of the reaction mixture with zinc in acetic acid. If we forgot this step, we would get substance V instead of substance D, which would probably explode when isolated.
