Vedclass · Answer

(C) $1$. $A$ chiral carbon is a carbon atom bonded to four different groups.$2$. The general structure of an amino acid is $R-CH(NH_2)-COOH$.$3$. For $Glycine$, the side chain $R$ is a hydrogen atom $(-H)$.$4$. Thus, the structure of $Glycine$ is $H-CH(NH_2)-COOH$, which means the central carbon is bonded to two identical hydrogen atoms.$5$. Since it does not have four different groups attached to the central carbon, $Glycine$ is achiral.
