Compound D, C7H14O, has an 1H-NMR spectrum that exhibits absorption in the alkane region (1 to 2 ?) and shows a triplet at 2.8 ?. Treatment of D, first with aqueous acid and then with KMnO4, yields 2 carboxylic acids identified as acetic acid and pentanoic acid. (KMnO4 cleaves 1,2-diols to yield carboxylic acids.) Propose a structure for compound D. Don't worry about steriochemistry.
Calculate the equilibrium partial pressure of bromine gas. No approximations can be made because the equilibrium constant is too large. I2 (g) + Br2 (g) 2IBr (g)
If you used 0.165mL of acetic anhydride, and 0.167g of p-aminophenol what was the limiting reageant? How many moles of the non-limiting reageant remained after the reaction was complete
A metal (M) forms an oxide with the formula MO. If the oxide contains 63.97% O by mass, what is the identity of the metal. Express answer as a chemical symbol.
Draw a structural formula of an alkene or alkenes (if more than one) that undergo acid-catalyzed hydration and without rearrangement give 2-methyl-2-butanol as the MAJOR product.
An unknown acid has a molar mass of 90. g/mol and a mass composition of, 40%-C, 6.7%-H, and 53.3% -O. What is the molecular formula of the acid
