The following four structures are naturally occuring optically active compounds. Star (*) the asymmetric carbon atoms in these structures.
Step 1 of 3
For all time place least priority group away from us.
If the sequence 123 is clockwise then configuration is R.
If the sequence 123 is counter-clockwise then configuration is S.
a) The second carbon in serine is asymmetric. The amino group receives first priority, the –COOH group second priority, the -CH2OH group third, and the hydrogen fourth.
Here least priority group towards to us so this is found to be the (S) configuration
b) The C2 and C3 are asymmetric carbons in erythrose
