This molecule will undergo a bimolecular nucleophilic substitution reaction with hydroxide ion. Draw the major organic product of that reaction, including correct stereochemistry using wedges and dashes. CH3 H3C.... NaOH

A student weighed approximately 1.5 g of an unknown solid acid and carefully placed the sample in a clean, but not necessarily dry, 250.0 mL volumetric flask. The student added deionized water to the flask, swirled the solution until the solid acid dissolved, then added sufficient deionized water to fill the flask to the fill line. A volumetric pipet was used to transfer 25.00 mL of the resulting solution to an Erlenmeyer flask, and 2 – 3 drops of phenolphthalein were added.The student filled the sodium hydroxide buret and titrated the acid solution with standardized 0.1000 M NaOH to the first permanent faint pink color, then repeated the titration a second time.Your instructor will provide the mass of unknown solid acid, as well as the initial and final buret readings for the two titrations. From this data and the information above, you will be able to calculate the molar mass of the unknown acid.The unknown solid acid is diprotic; that is, there are two moles of ionizable H+ ions per…

When concentrated HCI (aq) was added to the reaction mixture, the color changed to purple. Which reactant is purple and why? a) [Co(H2O)6]²*(aq) is purple because it is a cobalt compound b) [Co(H2O)6]²*(ag) is purple because adding Cl (as HCI) shifted the reaction towards products c) HCl is purple because adding it turned the reaction purple d) [Co(H2O),ClĄ]? (aq) is purple because adding CI (as HCI) shifted the reaction towards products 10 words Tet Predictions: On Accessibility: Investigate D Focus Type here to search…

(Solution BII) Prepare 25.00 mL of ~4.000x10-4 M KMnO4 solution via dilution of Solution BI (~0.00100 M KMnO4). Using the appropriately sized volumetric pipet, transfer the required amount of your solution from (BI) into a 25.00 mL volumetric flask. Fill it to the mark with distilled water, stopper it and invert several times to mix. Measure the absorbance of this solution at wavelength of 530 nm, the wavelength where this compound absorbs light most strongly. (e = 2.098 x 103 dm3/mol cm) Calculate the molarity of solution BII Volume of stock BI added via pipette
