5. Organic chemists often utilize aluminum hydride reagents in the synthesis of complex molecules. In order to diminish the reactivity of a very powerful reducing agent, lithium aluminum hydride (LAH, Lit AIH4¯), one can react the compound with an alcohol, such as ethanol. This reaction occurs in two steps. In the first step, ethanol is deprotonated by a hydride ion. In the following step, the two resultant molecules react to form a Lewis acid-base adduct. This can occur up to three more times. Draw a complete mechanism for the transformation shown below using curved arrow notation. H Ie H-AI-H + EtOH I H H Le H-AI-H OEt + H₂

Order these chemical species by increasing pH of an 0.1 M aqueous solution of each. That is, imagine making an 0.1 M solution of each species. Select 1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions. Note for advanced students: for all charged species, you may assume the necessary counterions act as neither acids nor bases. relative pH of 0.1 M aqueous solution species H20 4 H,PO4 5 HNO2 (Choose one) ▼ NO, 7 ОН (Choose one) ▼ HF |(Choose one) ▼
