Question

give the R and S configuration notation of glyceraldehyde ​

Answer 1

Answer:

R and S configuration of glyceraldehyde

The circle is clockwise, which by step 4a tells us that this carbon has the 'R' configuration, and that this molecule is (R)-glyceraldehyde. Its enantiomer, by definition, must be (S)-glyceraldehyde. Next, let's look at one of the enantiomers of lactic acid and determine the configuration of the chiral center.
