Trimethylamine, \((CH_3)_3N\), is a common reagent. It interacts readily with diborane gas, \(B_2H_6\). The latter dissociates to \(BH_3\), and this forms a complex with the amine, \((CH_3)_3N \rightarrow BH_3\).The reaction between trimethylamine and borane is shown.**Chemical Reaction:**\[(CH_3)_3N + BH_3 \rightarrow (CH_3)_3N-BH_3\]Is the \(BH_3\) fragment a Lewis acid or a Lewis base? To decide this, answer the following questions:**Question:**Which of the following is a definition of a Lewis acid?- Proton donor- Electron pair acceptor- Proton acceptor- Electron pair donor**Diagram Explanation:**The diagram illustrates the interaction between trimethylamine (\((CH_3)_3N\)) and borane (\(BH_3\)), resulting in the formation of a coordination complex where the nitrogen atom in trimethylamine donates its electron pair to the boron atom in borane.

In the given reaction, trimethyl amine reacts with BH3 as: We have to find whether BH3 is a Lewis acid or a Lewis base. A Lewis acid is a substance that accepts electron pairs and a Lewis base is a substance that donates electron pairs. So, a Lewis acid is an electron pair acceptor. In the given reaction, (CH3)3N is donating an electron pair and BH3 is accepting that pair of electrons. Hence, BH3 is a Lewis acid. Hence, the correct option is: electron pair acceptor

3. Answer all sections (i) - (iv). 1 mole of ethanol (C2H5OH) and 1 mole of ethanoic acid (CH;COOH) were reacted at 25 °C, in a non- aqueous solvent, until equilibrium was reached. It was subsequently determined that 0.33 moles of ethanol remained at equilibrium. (i) Write an equation for the reaction. (ii) Write an expression for the equilibrium constant, Kc, for the reaction and calculate its value. Subsequently a further 3 moles of C2H5OH was added to the solution. (ii) Determine the concentrations of all the species present when equilibrium is restored.
Treat your data sets independently. Enter your data in two columns in a spreadsheet. Your goal is to plot In K vs. 1/T (remember to use the absolute temperature). To determine K, you need to calculate the concentrations of all species that appear in the equilibrium expression. Do this as follows: [COC142-]: Use Beer's Law to calculate this concentration ( = 572 L mol-1 cm-1). However, you need to "adjust" your measured absorbance. Since both compounds absorb at 692 nm, not all of the light absorbed is due to the blue, chloride species. A small amount is due to the pink, aquo complex. Fortunately, this is a small amount, but it becomes important when the concentration of the chloro complex is very low. To compensate, divide the absorbance of the [Co(H2O)6]2+ at 511 nm by 29 ( this is the ratio of the molar absorptivity of this complex at 512 nm to that at 692 nm) and subtract this value from every absorbance measurement in your data set.* Use this "adjusted" absorbance to calculate the…
