Interpretation Introduction

Interpretation: The mechanism for the given reaction should be explained.

Concept Introduction:

Optically active: Optical active molecule rotates the plane polarized light.

Racemization: it is the process in which the pure enantiomers are converted into a mixture of D and L forms of isomers.

Enantiomers: they are chiral molecules whose mirror images are not superimposable.

Chirality: It refers to a Carbon atom in a molecule that contains four different substituents.

D form: They are enantiomers which rotates plane polarized to clockwise direction.

L form: They are enantiomers which rotates plane polarized to anti-clockwise direction.

R and S nomenclature: it is used to assign the molecule using CIP rules.

The CIP rules are as follows:

Select the chiral carbon and assign the numbers according to the decreasing atomic mass of atoms attached to it.

If the numbering follows clockwise direction then the molecule is termed as R and if it follows anti-clockwise direction then molecule is termed as S.

Leaving group: it is the fragment that leaves the substrate in a chemical reaction with a pair of electrons.

Reagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4-1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer. a. Compare the solution concentrations expressed as ppm Zn and ppm Zn(NO3)2. Compare the concentrations expressed as M Zn and M Zn(NO3)2 - Which units allow easy conversion between chemical species (e.g. Zn and Zn(NO3)2)? - Which units express concentrations in numbers with easily expressed magnitudes? - Suppose you have an analyte for which you don't know the molar…
