Chapter 13, Problem 13.50P
Interpretation Introduction

Interpretation:

The synthesis of the target molecule from the given starting material is to be determined.

Concept introduction:

Retrosynthetic analysis involves considering the reaction sequence in reverse. The analysis starts with the product determining the precursor that can produce it when the reaction is carried out in the forward direction. The retrosynthesis step, called a transform, does not consider a specific reaction or reaction conditions for the reaction in the forward direction. The transform is represented by an open arrow (). It is a proposed undoing of a single reaction and dissects the target into a simpler precursor. This process is continued till an easily available or easily synthesized precursor is reached.

The synthesis in the forward direction is then determined on the basis of the structural differences and the functional groups to be incorporated or modified. The specific reaction and reaction conditions are determined at this stage.

Using the conditions of spontaneity to deduce the signs of AH and AS Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy AH and reaction entropy AS. Note: if you have not been given enough information to decide a sign, select the "unknown" option. reaction observations conclusions A This reaction is always spontaneous, but proceeds slower at temperatures above 120. °C. ΔΗ is (pick one) AS is (pick one) ΔΗ is (pick one) B This reaction is spontaneous except above 117. °C. AS is (pick one) ΔΗ is (pick one) This reaction is slower below 20. °C than C above.

Calculating the pH at equivalence of a titration Try Again Your answer is incorrect. 0/5 a A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of hydrocyanic acid is 9.21. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added. pH = 11.43] G 00. 18 Ar B•
