Interpretation Introduction

(a)

Interpretation:

The structure of ascorbic acid as it exists at the physiological pH (pH =7.4) is to be stated.

Concept introduction:

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

Interpretation Introduction

(b)

Interpretation:

The resonance structures of the structure of ascorbic acid as it exists at the physiological pH (pH =7.4) using curved-arrow notation are to be stated.

Concept introduction:

Resonance is the phenomena of the delocalization of pi electrons to give extra stability to the molecule. This extra stability comes from the distribution of the energy of the molecule in the resonance structures formed.

The preceding equation for the protonation of acetamide shows a hypothetical product that is not actually formed. When acetamide is protonated by a strong enough acid, it does not protonate on nitrogen, but at a different basic site. Draw the structure of the actual conjugate acid of acetamide, and explain (resonance) why protonation occurs where it does rather than on nitrogen. Calculate the pKa of this conjugate acid.
Thiocyanic acid (HSCN) is an inorganic acid (pKa = 1.1 at 25 °C) that can be classified as “strong” largely due to resonance stabilization of its conjugate base, thiocyanate (SCN– ). In the space provided below, draw Lewis electron dot structures of SCN- and all of its important resonance forms.
The compound acetophenone has a very similar molar mass to that of benzoic acid and benzamide. However, acetophenone has a much lower m.p. (20 °C) than both such that, by contrast, it is a liquid at room temperature. By considering intermolecular forces and comparing functional group structure, account for this big difference in physical properties.
