Concept explainers
(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.
(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
(c)
Interpretation:
The hypothesis in part (b) is to be verified using NMR spectroscopy assuming both the samples
Concept introduction:
Spectroscopy method is used to identify the structure of the molecule. It is based on the interactions between matter and
