Interpretation Introduction

a) 2-cyclohexanone

Interpretation:

The product obtained in the base catalyzed Michael reaction of 2, 4-pentanedione with 2-cyclohexanone (α, β- unsaturated acceptor) is to be given.

Concept introduction:

Michael reaction involves the conjugate addition of a stable enolate ion derived from a β-ketoesters or β- diketones or β- ketonitriles or malonic esters (donors) to an unhindered α,β- unsaturated ketones or aldehydes or esters or thioesters or nitriles or amides or nitro compounds (acceptors). The enolate ion from the donor attacks the double bond in acceptor. A new bond is formed between the α-carbon of the donor and the β- carbon of the unsaturated ester.

To give:

The product obtained in the base catalyzed Michael reaction of 2, 4-pentanedione with 2-cyclohexanone (α, β- unsaturated acceptor).

Interpretation Introduction

b) Propenenitrile

Interpretation:

The product obtained in the base catalyzed Michael reaction of 2, 4-pentanedione with propenenitrile (α, β- unsaturated acceptor) is to be given.

Concept introduction:

Michael reaction involves the conjugate addition of a stable enolate ion derived from a β-ketoesters or β- diketones or β- ketonitriles or malonic esters (donors) to an unhindered α,β- unsaturated ketones or aldehydes or esters or thioesters or nitriles or amides or nitro compounds (acceptors).

d. In Figure 4, each stationary phase shows some negative correlation between plate count and retention factor. In other words, as k' increases, N decreases. Explain this relationship between k' and N. Plate Count (N) 4000 3500 2500 2000 1500 1000 Figure 4.
