Identify the absolute configuration of the chirality centers in each of the following compounds as R or S. Note: if multiple chirality centers are present, indicate the stereochemical designations as: RR, SS, RS, or SR. (Other terms used for chirality center include chiral center, stereocenter, and stereogenic center.) CO2H HW HO CH3 он
Indicate whether the pair of structures shown represent stereoisomers, constitutional isomers, different conformations of the same compound, or the same conformation of a compound viewed from a different perspective. Note that cis, trans isomers are an example of stereoisomers. CH3 CH3 CH3 Ć Ći Click on all of the carbon chirality centers in the molecule below.

in the picture, why isnt the carbon that i circled considered a
chiral center? doesnt it have four unique groups attatched to it?
please help
