Compound A has the molecular formula C14H25Br and was obtained by reaction of sodium acetylide with 1,12-dibromododecane. On treatment of compound A with sodium amide, it was converted to compound B (C14H24). Ozonolysis of compound B gave the compound with the following chemical formula: HO2C(CH2)12COOH (a diacid because it has two acid functional groups on each end). Catalytic hydrogenation of compound B over Lindar palladium gave compound C (C14H26) and hydrogenation of compound B over platinum gave compound D (C14H28). Sodium-ammonia reaction of compound B gave compound E (C14H26). Both C and E yielded O=CH(CH2)12CH=O on ozonolysis. Assign structures to compounds A through E so as to be consistent with the observed transformations.
The initial temperature of the calorimeter is 23.0. If 6.30 of is added to the calorimeter, what will be the final temperature of the solution in the calorimeter?
A 1.348 gram sample containing an unknown amount of arsenic trichloride and the rest inerts was dissolved into a NaHCO3 and HCl aqueous solution.
An environmental engineer tells you that adjusting the pH to 8.5 will decrease total soluble Cr(III) to below 1 mg/L (1.92 x 10-5 M). Is this true? In other words, is the solubility of Cr(III) in the presence of Cr(OH)3(s) at a pH of 8.5 ? 1 mg/L.
