The product of the following transformation has to be drawn, and show the single steroisomer product of this transformation. Also the most stable possibel chair species should be identifed. Concept Introduction: Stereoisomers are isomers which have different spatial arrangement in spite of same bond connectivity. Stereoisomers are due to the presence of sterocenters. Stereo center may be an atom axis (bond) or plane from which interchanging of two groups leads to stereoisomers. Asymmetric center is a sterocenters which arises to hydrocarbons if the carbon is bonded to four different groups. Anomers are represented as α and β forms, if the conformation of the farthest right-hand carbon or anomeric carbon in the Haworth ring is such that the OH group points down (is on the opposite side of the ring from the –CH 2 OH group), the structure is called the α -form. If the –OH group points up, it’s called a β -form.

Interpretation Introduction

Interpretation:

The product of the following transformation has to be drawn, and show the single steroisomer product of this transformation. Also the most stable possibel chair species should be identifed.

Concept Introduction:

Stereoisomers are isomers which have different spatial arrangement in spite of same bond connectivity. Stereoisomers are due to the presence of sterocenters. Stereo center may be an atom axis (bond) or plane from which interchanging of two groups leads to stereoisomers.

Asymmetric center is a sterocenters which arises to hydrocarbons if the carbon is bonded to four different groups.

Anomers are represented as α and β forms, if the conformation of the farthest right-hand carbon or anomeric carbon in the Haworth ring is such that the OH group points down (is on the opposite side of the ring from the –CH₂OH group), the structure is called the α-form. If the –OH group points up, it’s called a β-form.

Which of the following statements is correct? A) The haloform reaction proceeds under very difficult conditions and the yield is very low. B) The haloform reaction is used only for the identification of compounds containing secondary alcohol groups. C) Methyl ketones or alcohols are oxidized with halogens in acidic solutions to give carboxylic acids and the appropriate haloform product. D) Enolate anions react rapidly with halogens to give alpha-halocarbonyl compounds.

The following substances can be prepared by a nucleophilic addition reaction between an aldehyde or ketoneand a nucleophile. Identify the reactants from which they were prepared. If the substance is an acetal, identifythe carbonyl compound and the alcohol; if it is an imine or enamine, identify the carbonyl compound and theamine. You do not have to consider stereochemistry. In cases where there is more than one answer, just giveone. Use Grignard reagents when an organometallic reagent is required. Draw the Grignard reagent as acovalent magnesium bromide.
