Question

Which of the following represent the correct molecular formula of chlorophyll-b?

• A. $C_{55}{H}_{72}{O}_6{N}_{4}Mg$
• B. $C_{55}{H}_{72}{O}_5{N}_{4}Mg$
• C. $C_{55}{H}_{72}{O}_4{N}_{4}Mg$
• D. $C_{55}{H}_{70}{O}_5{N}_{4}Mg$
• E. $C_{55}{H}_{70}{O}_6{N}_{4}Mg$

Answer 1

The correct option is E $C_{55}{H}_{70}{O}_6{N}_{4}Mg$

Chlorophyll b helps in photosynthesis by absorbing light. It is more soluble than chlorophyll a in a polar solvent because of its carbonyl group.

So correct option is 'Option E'.
