Interpretation:
Whether the given transformation requires hydroxyl to protect it is to be determined.
Concept introduction:
The protecting groups are used to make the specific
(b)
Interpretation:
Whether the given transformation required hydroxyl to protect it is to be determined.
Concept introduction:
The protecting groups are used to make the specific functional group temporarily unreactive in a poly-functional group molecule under reaction conditions needed to make modifications in other functional group in the molecule. The protecting group can be removed once the desired reaction is carried out and restore the original functional group.

- Indicate the compound resulting from adding NaOH cyclopentane-CH2-CHO.arrow_forwardUse the provided information to calculate Kc for the following reaction at 550 °C: H2(g) + CO2(g) ⇌ CO(g) + H2O(g) Kc = ?CoO(s) + CO(g) ⇌ Co(s) + CO2(g) Kc1 = 490CoO(s) + H2(g) ⇌ Co(s) + H2O(g) Kc2 = 67arrow_forwardCalculate Kc for the reaction: I2 (g) ⇋ 2 I (g) Kp = 6.26 x 10-22 at 298Karrow_forward
- For each scenario below, select the color of the solution using the indicator thymol blue during the titration. When you first add indicator to your Na2CO3solution, the solution is basic (pH ~10), and the color is ["", "", "", "", ""] . At the equivalence point for the titration, the moles of added HCl are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCl begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is ["", "", "", "", ""] . When you weren't paying attention and added too much HCl (~12 mL extra), the color is ["", "", "", "", ""] . When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color isarrow_forwardTo convert cyclopentane-CH2-CHO to cyclopentane-CH2-CH3, compound A is added, followed by (CH3)3CO-K+, DMS at 100oC.

- 2. Write a reasonable mechanism that converts the reactants into the products. Avoid issues A-U from the previous page. You can use any number of steps (it does not have to be a one-step mechanism). Do not use any other chemicals (solvents, acids, bases, etc.) in your mechanism. 2 2 H ΗΘarrow_forwardFor the following reaction, the partial pressures were determined for the reaction components as shownbelow. Is the reaction at equilibrium? If not, in which direction will it proceed?I2 (g) + Cl2 (g) ⇋ 2 ICl (g) Kp = 81.9 partial pressures: I2 = 0.114 atm; Cl2 = 0.102 atm; ICl = 0.355 atmarrow_forwardDraw the major product of this reaction.
