For the following SN2 reaction, draw the major organic product and select the correct (R) or (S) designation around the stereocenter carbon in the organic substrate and organic product. Include wedge/dash bonds and H on a stereocenter.
The correct (R) or (S) designations for the stereocenter carbons are:
The organic substrate is (S) and the organic product is (R).
The organic substrate is (R) and the organic product is (S)
The organic substrate and organic product are both (S)
The organic substrate and organic product are both (R)
Since it is an example for sn2 reaction, inversion of configuration occured.
Starting material has R configuration and product shiush be S configuration (opposite to R).
If least priority group ( H) is on above the plane,then we should consider opposite configuration. Here in the product, HHis on above the plane hence anticlockwise direction is considered.
