The optically active compounds among the given compounds are to be identified. Concept introduction: The molecules that are non-superimposable or not identical with their mirror images are known as chiral molecules. A pair of two mirror images that are non-identical is known as a pair of enantiomers, and these are optically active. The enantiomers in which the path traced from the highest to the lowest atomic number is in the anticlockwise direction are designated as S provided that among the four groups attached to the chiral carbon, the least priority group is in horizontal position in Fischer projection. The enantiomers in which the path traced from the highest to the lowest atomic number is in the clockwise direction are designated as R provided that among the four groups attached to the chiral carbon, the least priority group is in horizontal position in Fischer projection. . The objects or molecules which are superimposable with their mirror images are achiral objects or molecules. These objects have a centre of symmetry or plane of symmetry. The achiral compounds in which the plane of symmetry is present internally and consists of chiral centres are known as meso compounds, but they are optically inactive.

Interpretation Introduction

Interpretation:

The optically active compounds among the given compounds are to be identified.

Concept introduction:

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

A pair of two mirror images that are non-identical is known as a pair of enantiomers, and these are optically active.

The enantiomers in which the path traced from the highest to the lowest atomic number is in the anticlockwise direction are designated as S provided that among the four groups attached to the chiral carbon, the least priority group is in horizontal position in Fischer projection.

The enantiomers in which the path traced from the highest to the lowest atomic number is in the clockwise direction are designated as R provided that among the four groups attached to the chiral carbon, the least priority group is in horizontal position in Fischer projection. .

A pdf file of your hand drawn, stepwise mechanisms for the reactions. For each reaction in the assignment, you must write each mechanism three times (there are 10 reactions, so 30 mechanisms). (A) do the work on a tablet and save as a pdf., it is expected to write each mechanism out and NOT copy and paste the mechanism after writing it just once. Everything should be drawn out stepwise and every bond that is formed and broken in the process of the reaction, and is expected to see all relevant lone pair electrons and curved arrows.
