(a)

Interpretation Introduction

Interpretation:

The reaction sequences that are followed in the formation of the product with the given reactants has to be written.

(b)

Interpretation Introduction

Interpretation:

The reaction sequences that are followed in the formation of the product with the given reactants has to be written.

Concept Introduction:

The reagent Na / NH3 is used for the conversion of Alkynes to trans alkenes.  The reaction mechanism is the sodium forms the radical-anion in the Alkyne and then, a proton is transferred from the ammonia to the radical-anion.  The second atom in the sodium is transferred to form the carbanion.  The carbanion is neutralized by the proton of the ammonia.

(c)

Interpretation Introduction

Interpretation:

The reaction sequences that are followed in the formation of the product with the given reactants has to be written.

(d)

Interpretation Introduction

Interpretation:

The reaction sequences that are followed in the formation of the product with the given reactants has to be written.

(e)

Interpretation Introduction

Interpretation:

The reaction sequences that are followed in the formation of the product with the given reactants has to be written.

Concept Introduction:

The reagent (sia)2BH is known as Disimylborane.  It is used for chemo and regioselective hydroboration reactions.  This reagent is more selective for terminal hydroboration.

You have now performed a liquid-liquid extraction protocol in Experiment 4. In doing so, you manipulated and exploited the acid-base chemistry of one or more of the compounds in your mixture to facilitate their separation into different phases. The key to understanding how liquid- liquid extractions work is by knowing which layer a compound is in, and in what protonation state. The following liquid-liquid extraction is different from the one you performed in Experiment 4, but it uses the same type of logic. Your task is to show how to separate apart Compound A and Compound B. . Complete the following flowchart of a liquid-liquid extraction. Handwritten work is encouraged. • Draw by hand (neatly) only the appropriate organic compound(s) in the boxes. . Specify the reagent(s)/chemicals (name is fine) and concentration as required in Boxes 4 and 5. • Box 7a requires the solvent (name is fine). • Box 7b requires one inorganic compound. • You can neatly complete this assignment by hand and…
