Description: In the SN2 reaction, nucleophiles attack from the back side of the carbon. So the product assumes a stereochemical position opposite to the leaving group.

Question

Identify the type of following $3$ -D representation (I) and (Il) of a molecule and state significance of the lines drawn.

Accepted Answer

There are two representations to represent the configuration of chiral carbon atom and the three-dimensional structure of optical isomers on plane paper: (a) Fischer projection formula (b) Wedge formula.

The representation $I$ represents the wedge formula of the compound: The bonds in the plane of the paper are represented by normal lines, the bonds projecting above the plane of paper are represented by solid wedges, and the bonds going below the plane of paper are represented by broken wedges.

The representation $II$ represents the Fischer projection formula, and this convention is used to depict a stereoformula in two dimension without destroying the absolute configuration at chiral centres. The chiral centre is on the plane of the paper, two bonds are coming out of the plane of the paper and are on a horizontal plane, the two remaining bonds are going into the plane of the paper and are on a vertical plane.

Identify the type of following $3$ -D representation (I) and (Il) of a molecule and state significance of the lines drawn.
