Textbook Problem

The structure of vitamin C, whose chemical name is ascorbic acid, is drawn below (without lone pairs of electrons).

(a) What is the approximate value for the O—C—O bond angle?

(b) There are four OH groups in this structure. Estimate the C—O—H bond angles for these groups. Will they be the same value (more or less), or should there be significant differences in these bond angles?

(c) Is the molecule chiral? How many chiral carbon atoms can be identified in this structure?

(d) Identify the shortest bond in this molecule.

(e) What are the functional groups of the molecule?

(a)

Interpretation Introduction

Interpretation:

The approximate value for the O - C - O bond angle has to be determined.

Concept introduction:

Hybridization is the mixing of valence atomic orbitals to get equivalent hybridized orbitals that having similar characteristics and energy.

Geometry of a molecule can be predicted by knowing its hybridization.

sp3  hybrid orbitals is produced by hybridization of single s-orbital and three p-orbital. It has tetrahedral geometry

sp2  hybrid orbitals is produced by hybridization between one s-orbital and two p-orbitals. It has trigonal-planar geometry

sp  hybrid orbitals is produced by hybridization of single s-orbital and single p-orbital. It has linear geometry

Explanation

The structure of vitamin C is,

In OCO, the carbon atom is sp

(b)

Interpretation Introduction

Interpretation:

The bond angles for the four -OH groups have to be estimated.

(c)

Interpretation Introduction

Interpretation:

The chiral carbon in the molecule has to be determined

Concept introduction:

A chiral carbon is the carbon atom which is substituted to four different groups. Due to presence of chiral carbon a molecule become chiral and it gives optical isomers also that is R and S isomers. For example,

  images

All the substituents are different hence is is a chiral carbon and so molecule.

(d)

Interpretation Introduction

Interpretation:

The shortest bond in the molecule has to be determined

Concept introduction:

Bond order: It is the measure of number of electron pairs shared between two atoms.

Bondorder=12(NumberofelectronsinbondoingMOs-NumberofelectronsinantibondingMOs)

Bond length is inversely proportional to the bond order.

A higher bond order results in a shorter bond for a given pair of atoms.

(e)

Interpretation Introduction

Interpretation:

The functional group in the molecule has to be identified.
