Vedclass · Answer

(C) Chlorophyll '$a$' and chlorophyll '$b$' are the primary photosynthetic pigments.Chlorophyll '$a$' has the molecular formula $C_{55}H_{72}O_5N_4Mg$ and contains a methyl group $(-CH_3)$ at the third carbon position of the porphyrin ring.Chlorophyll '$b$' has the molecular formula $C_{55}H_{70}O_6N_4Mg$ and contains an aldehyde group $(-CHO)$ at the same position.Therefore,the presence of a $-CH_3$ group in chlorophyll '$a$' and a $-CHO$ group in chlorophyll '$b$' is the key structural difference.
