The absolute configuration of is:

Options

  1. A2 S , 3 S
  2. B2 R , 3 R
  3. C2 R , 3 S
  4. D2 S , 3 R

Correct answer

D. 2 S , 3 R

Step-by-step solution

at 2 Carbon Rotation is clockwise, but lowest priority group is on horizontal line so configuration will be S at 3 Carbon Rotation is anticlockwise and lowest priority group is on horizontal line so, configuration will be R ∴ Configuration is 2 S ,   3 R .
