In the box below draw the tetrahedral representation of the s enantiomer of the amino acid valine, ch3ch(ch3)ch(nh2)co2h.

The S-Enantiomer of Valine is attached below.

Assigning S-Configuration:

                                            In Valine there is only one chiral carbon (carbon to which all bonded atoms or group of atoms attached have different masses). This carbon also known as alpha carbon has a tetrahedral geometry. For S-configuration, according to Cahn Ingold Prelog Rules the -NH₂ group is assigned with priority order of 1, The carbon of carboxylic acid is assigned the number two and the tertiary carbon is assigned with number three. These three groups are made in such a way that moving from number 1 to number 3 makes a S sign or anticlockwise rotation while keeping the hydrogen atom behind the plane.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

is there any options? maybe im just not seeing them but i need the options to
