Chapter 3, Problem 3.51AP
Interpretation Introduction

(a)

Interpretation:

The first and second ionization equations of the malonic acid are to be stated with the pKa value of each ionization.

Concept introduction:

The pKa value of the acid is known as acid dissociation constant. It tells about the extent of dissociation of acid. Lower is the pKa value of the acid, higher is the extent of dissociation of the acid.

Interpretation Introduction

(b)

Interpretation:

The ionization state of the malonic acid is to be stated at pH=4.3.

Concept introduction:

The pKa of the acid represents the pH at which the acid will be found in the protonated form or dissociated form. The acid is found in the dissociated form in the pH range equal to pKa1 to pKa+1.

Interpretation Introduction

(c)

Interpretation:

The number of moles of base per mole of malonic acid required to adjust the pH=4.3 is to be stated.

Concept introduction:

The pKa of the acid represents the pH at which the acid will be found in the protonated form or dissociated form. The acid is found in the dissociated form in the pH range equal to pKa1 to pKa+1.

Interpretation Introduction

(d)

Interpretation:

The reason as to why the first pKa of malonic acid is much lower than the pKa of acetic acid, but the second pKa of malonic acid is much higher than the pKa of acetic acid is to be stated.

Concept introduction:

The pKa value of the acid is known as acid dissociation constant. It tells about the extent of dissociation of acid. Lower is the pKa value of the acid, higher is the extent of dissociation of the acid.

Interpretation Introduction

(e)

Interpretation:

An explanation as to how the difference between the first and second pKa values of the dicarboxylic acid changes with the increase in the value of n is to be stated.

Concept introduction:

The pKa value of the acid is known as acid dissociation constant. It tells about the extent of dissociation of acid. Lower is the pKa value of the acid, higher is the extent of dissociation of the acid.

Identify the missing starting materials/ reagents/ products in the following reactions. Show the stereochemistry clearly in the structures, if any. If there is a major product, draw the structures of the major product with stereochemistry clearly indicated where applicable. Show only the diastereomers (you do not have to draw the pairs of enantiomers). If you believe that multiple products are formed in approximately equal amounts (hence neither is the major product), draw the structures of the products, and show the detailed mechanism of these reactions to justify the formation of the multiple products. If you believe no product is formed, explain why briefly. (6 mark for each, except f and g, which are 10 mark each)
3. What starting material would you use to synthesize 3-hydroxypentanoic acid using a NaBH4 reduction?
1. Give stereochemical (Fischer projection) formulas for all (but no extras) the stereoisomers that could theoretically form during the reduction of a. the carbonyl group of 2-methyl-3--pentanone b. both carbonyl groups of 2,4-pentanedione (careful!) 2. Predict the products of the reduction of O=CCH2CH2CH2C=O with a. LiAlH4 b. NaBH4 CH3 OH
