The upcoming discussion will update you about the differences between chlorophyll a and chlorophyll b.
Chlorophyll a:
1. Chemically it is C55H72O5N4Mg
2. Its Carbon 3 contains methyl group
3. Blue green colour in pure state.
4. Soluble in petroleum ether
5. It absorbs more red wave length
6. It is primary photosynthetic pigment
Chlorophyll b:

2. Carbon 3 contains aldehyde group
3. Oliver green colour in pure state.
4. Soluble in methyl alcohol
5. Absorbs more violet blue wave length
6. It is accessory photosynthetic pigment
