The NMR spectrum of CH 3 CH 2 Cl , by giving the approximate location of each NMR signal is to be sketched. Concept introduction: The number of NMR signal in a compound is equal to the number of chemically non-equivalent protons present in that compound. Protons which are present in the same chemical environment that is between the same groups of atoms are known as chemically equivalent protons. The more the shielded proton less will be its chemical shift value and the corresponding signal will be produced at the right-hand side or lower frequency region or vice versa.

Question

when performing the reaction that involves 2 equivalents of 3-(diethylamino)-phenol and Phthalic anhydride with sulfuric acid and water react to form rhodamine b where the Phthalic anhydride cleaves in acid and how does Excessive Washing (w/ Base) & Subsequent Resonance Structure get affected

Using the general properties of equilibrium constants At a certain temperature, the equilibrium constant K for the following reaction is 1.3 × 10 4: Cl2(g) + CHCl3(g) HCl(g) + CC₁(g) Use this information to complete the following table. Suppose a 16. L reaction vessel is filled with 1.6 mol of HCI and 1.6 mol of CCl4. What can you say about the composition of the mixture in the vessel at equilibrium? There will be very little Cl2 and CHCl3. ☐ x10 There will be very little HCI and CCl4. Neither of the above is true. What is the equilibrium constant for the following reaction? Be sure your answer has the correct number of significant digits. HCl(g)+CC14(g) 12 Cl2(9)+CHCl3(9) K = 0 ☐ What is the equilibrium constant for the following reaction? Be sure your answer has the correct number of significant digits. 2 Cl₂(9)+2CHCl3(9) 2 HCl(9)+2CC₁₁(9) K = ✓ 00. 18 Ar
