Question

Bacterio-chlorophyll a is represented as..

• A. $C_{55}{H}_{74}{O}_6{N}_{4}Mg$
• B. $C_{55}{H}_{70}{O}_6{N}_{4}Mg$
• C. $C_{55}{H}_{72}{O}_5{N}_{4}Mg$
• D. $C_{35}{H}_{32}{O}_5{N}_{4}Mg$

Answer 1

The correct option is A $C_{55}{H}_{74}{O}_6{N}_{4}Mg$

Bacteriochlorophyll is photosynthetic pigment present in bacteria. It has chemical formula C${}_{55}$H${}_{74}$O${}_6$N${}_4$Mg. Chemical formula for chlorophyll a is C${}_{55}$H${}_{72}$O${}_5$N${}_4$Mg. Chemical formula for chlorophyll b is C${}_{55}$H${}_{70}$O${}_6$N${}_4$Mg.

Thus, the correct answer is option A.
