Explain what products would you observe if you tried to prepare a Grignard reagent from 4-bromo1-butanol? They give us a hint that says 4-hydroxybutylmagnesium bromide isn't the final product. First off I know that is presumed to react with the OH but we don't know what the reaction is doing otherwise.
When extracting an organic compound from an aqueous solution into an organic solvent, e.g., diethyl ether, a chemist will sometimes add sodium chloride to the aqueous solution. What is the purpose of such an addition, and what is the procedure cal..
calculate the pH of pure water at 298 K and 403 K. Recall that pH is defined in terms of activity not concentration.
The half-life for a first-order reaction is known to be 379 seconds at a given temperature. What is the rate constant at this temperature?
A 2.650 mol quantity of NOCL was primarily placed in a 1.450 L reaction chamber at 400 C. After equilibrium was established, it was found that 27.10 percent had disassociated.
Calculate the half-life (in s) of a first-order reaction if the concentration of the reactant is 0.0654 M 18.4 s after the reaction starts and is 0.0112 M 82.9 s after the reaction starts.
