Question

Molecular formula of chlorophyll b is:

• A. $C_{55}{H}_{70}{O}_6{N}_{4}Mg$
• B. $C_{55}{H}_{72}{O}_5{N}_{4}Mg$
• C. $C_{55}{H}_{70}{O}_5{N}_{4}Mg$
• D. $C_{54}{H}_{70}{O}_6{N}_{4}Mg$

Answer 1

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

Chlorophyll b is a form of chlorophyll. Chlorophyll b helps in photosynthesis by absorbing light energy. Its colour is green and it primarily absorbs blue light. It is insoluble in water and soluble in ethanol, ether. Its molar mass is 907.492gmol⁻¹ and the chemical formula is $C_{55}{H}_{70}{O}_6{N}_{4}Mg$.

Option A is correct.
