Interpretation Introduction

Interpretation:

The substructure that would have an R designation is to be drawn from the given structure.

Concept Introduction:

▸ The molecules which are non-superimposable or not identical with their mirror images are known as chiral molecules.

▸ A pair of two mirror images which are non-identical is known as enantiomers which are optically active.

▸ The objects or molecules which are superimposable with their mirror images are achiral objects or molecules and these objects have a centre of symmetry or plane of symmetry.

▸ The achiral compounds in which plane of symmetry is present internally and consists of chiral centres are known as meso compounds but they are optically inactive.

▸ The stereoisomers which are non-superimposable on each other and not mirror images of each other are known as diastereomers.

▸ Chiral molecules are capable of rotating plane polarized light

▸ The molecules which are superimposable or identical with their mirror images are known as achiral molecules, and achiral molecules are not capable of rotating the plane-polarised light.

▸ Priority is given to all the four group attached to the chirality center.

▸ Priority is assigned on the basis of the atomic number of the atom. Higher the atomic number, higher will be its priority.

▸ If priority cannot be assigned according to atomic mass, then, it is assigned according to first point of difference.

▸ After assigning priority to the four groups, rotate the molecule such that fourth priority group is away from the observer.

▸ Now, move from a to b to c; if the direction is clockwise, then the chiral center designated as (R) and if the direction is anticlockwise, then the chiral center designated as (S).

If there is no reagent that will make your desired product in good yield or without complications, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. There is no reagent that will make this synthesis work without complications. : ☐ S ☐

Predict the major products of this organic reaction: H OH 1. LiAlH4 2. H₂O ? Note: be sure you use dash and wedge bonds when necessary, for example to distinguish between major products with different stereochemistry. Click and drag to start drawing a structure. G C टे

For each reaction below, decide if the first stable organic product that forms in solution will create a new C-C bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. NH2 CI MgCl ? Will the first product that forms in this reaction create a new CC bond? Yes No MgBr ? Will the first product that forms in this reaction create a new CC bond? Yes No G टे
