Molecular formula of chlorophyll-b is
Options
- AC ₅₅ H ₇₀ O ₆ ~N ₄ Mg
- BC ₅₅ H ₇₂ O ₅ ~N ₄ Mg
- CC ₅₅ H ₇₀ O ₅ ~N ₄ Mg
- DC ₅₄ H ₇₀ O ₆ ~N ₄ Mg
Correct answer
A. C ₅₅ H ₇₀ O ₆ ~N ₄ Mg
Step-by-step solution
The molecular formula of chlorophyll-b is C ₅₅ H ₇₀ O ₆ ~N ₄ Mg . It helps in photosynthesis by absorbing light energy. It is more soluble in polar solvents than chlorophyll-a because of its carbonyl group. It is of yellow colour and primarily absorbs blue light.
