Question

Chapter 19, Problem 19.68AP

Interpretation Introduction

(a)

Interpretation:

The reason as to why the two forms of cyclic trimer analogous to paraldehyde are known is to be stated.

Concept introduction:

Trichloroacetaldehyde is also known as chloral or trichloroethanal. The compound trichloroactealdhyde is mainly used as a main ingredient for the preparation of the insecticide DDT.

Interpretation Introduction

(b)

Interpretation:

Out of the two trimers of chloroacetaldehyde one with the higher melting point is to be stated.

Concept introduction:

The melting point is that temperature at which a solid will melt. At the melting point both the phases liquid and solid exist at equilibrium. The melting point gives the idea o the packing of the solid. The melting point of ice is −273.15 K.

Interpretation Introduction

(c)

Interpretation:

The hypothesis in part (b) is to be verified using NMR spectroscopy assuming both the samples α−parachloral and β−parachloral are in hand.

Concept introduction:

Spectroscopy method is used to identify the structure of the molecule. It is based on the interactions between matter and electromagnetic radiations. Proton NMR spectroscopy identifies the number of hydrogen atoms present in a molecule and the nature of the functional group. The value of chemical peaks depends upon the chemical environment.
