At 0°C, the following product composition is observed: product A (80%), product B (20%). At 100°C, the following product composition is observed: product A (25%), product B (75%). 6. Why does addition product A predominate at the lower temperature (0°C)? A. The reaction is equilibrium controlled: product A is more stable than product B, so product A predominates. B. The reaction is kinetically controlled: product A forms faster, so product A predominates. C. Product A predominates because it has more ] electron delocalization than product B. D. Product A is less sterically hindered, so it predominates.

Organotin compounds play a significant role in diverse industrial applications. They have been used as plastic stabilizers and as pesticides or fungicides. One method used to prepare simple tetraalkylstannanes is the controlled direct reaction of liquid tin(IV) chloride with highly reactive trialkylaluminum compounds, such as liquid triethylaluminum (Al(CzHs)3). 3SnCl4 + 4Al(C2H5)3 → 3Sn(C2H5)4 + 4AlCl3 In one experiment, 0.160 L of SnCl4 (d= 2.226 g/mL) was treated with 0.346 L of triethylaluminum (Al(C2H5)3); d = 0.835 g/mL). What is the theoretical yield in this experiment (mass of tetraethylstannane, Sn(C2H5)4)? If 0.257L of tetraethylstannane (d= 1.187 g/mL) were actually isolated in this experiment, what was the percent yield?
In some nucleophilic substitutions under SN1 conditions, complete racemization does not occur and a small excess of one enantiomer is present. For example, treatment of optically pure 1-bromo-1-phenylpropane with water forms 1-phenylpropan-1-ol. (a) Calculate how much of each enantiomer is present using the given optical rotation data. (b) Which product predominates—the product of inversion or the product of retention of configuration? (c) Suggest an explanation for this phenomenon.

1)Chemistry students are taking an experimental course in organic chemistry at a public university. 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.

The 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.
