The aptitude of a frustrated Lewis pairs to capture NO nitric oxide to produce aminoxyl radicals is a recent triumph of FLP chemistry, where Mes is 1,3,5-trimethylphenyl.
Name some factors, besides weight and cost effectiveness, that one might consider when choosing one brand of antacid over another. Explain.
Ozonolysis of a single enantiomer of R produces S, an acyclic, optically active ketoaldehyde of formula C6H10O2. Propose structures for compounds Q, R, and S. Do not label them; simply draw all three of them in the space provided in any order.
A gaseous mixture of O2, H2, and N2 has a total pressure of 1.50 atm and contains 8.20 g of each gas. Find the partial pressure of each gas in the mixture.
