d. S isomer.

Step by step solution

01

R and S nomenclature

The R and S nomenclature is assigned to the given molecule as follows:

  • The molecules having high molecular masses are given as the first priority.


The order of the priority of some groups is: H<C<N<O<S<Cl<Br<I

  • The double bonded groups also have the highest priority because it is multiplied by the same group in the place of a bond. For example, C=O is equivalent to CC-OO.
  • The clockwise movement based on the priority gives R configuration, and the anticlockwise movement gives S configuration.

If the lowest priority group is above the plane, then the R is inverted into S and vice versa.

02

Explanation

a. The order of priority is shown as:

Br>Cl>CH3>H

Therefore, the movement is anticlockwise.

Representation of S isomer

b. The order of priority is shown as:

OH>COOH>CH3>H

Therefore, the movement is anticlockwise.

c. The order of priority is shown as:

CH2CH2CH(CH3)CH>CH2CH2CH2CH2>CH3>H

Therefore, the movement is clockwise.

Representation of R isomer

d. The order of priority is shown as:

OH>CH2Cl>CH2CH2Br>CH3

Therefore, the movement is clockwise.
