Why is chlorophyll soluble in organic solvents?
Chlorophyll is a magnesium-porphyrin compound that consists of a ring porphyrin (head) and a long hydrocarbon phytol (tail), both of which are bonded together by an ester bond [5]. Chlorophyll is water-insoluble, but can be easily dissolved in organic solvents such as ethanol, acetone, ether, and chloroform [5].
Which chlorophyll is soluble in water and insoluble in organic solvent?
Chlorophyll b has much the same solubility properties as chlorophyll a, except that the solubility is generally slightly less. It is completely insoluble in petrol ether and practically insoluble in 90\% methyl alcohol. ‘ For further information on the chemistry of chlorophyll see Willstatter and Stoll (1913).
Is chlorophyll soluble in organic solvent?
THE green colouring matter of plants is a wax-like material of complex chemical structure to which the name chlorophyll was given by Pelletier and Caventou in 1817. It is insoluble in water but soluble in alcohol, ether and other organic solvents.
What are insoluble in water but soluble in organic solvents?
Ionic compounds are generally insoluble in water but soluble in organic solvents.
Why is chlorophyll water insoluble?
The basic structure of chlorophyll is a porphyrin ring similar to that of heme in hemoglobin, although the central atom in chlorophyll is magnesium instead of iron. The long hydrocarbon (phytol) tail attached to the porphyrin ring makes chlorophyll fat-soluble and insoluble in water.
Why Chlorophyll a is more soluble?
At carbon 3 in chlorophyll a methyl group is present while in chlorophyll b aldehydic group is present due to which chlorophyll b becomes more polar than chlorophyll a.
Why chlorophyll is insoluble in water?
Is chlorophyll a soluble in water?
Chlorophyll a
| Names | |
|---|---|
| Solubility in water | Insoluble |
| Solubility | Very soluble in ethanol, ether Soluble in ligroin, acetone, benzene, chloroform |

| Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). |
Why are organic compounds soluble in organic solvents?
Organic compounds tend to dissolve well in solvents that have similar properties to themselves. This principle is often referred to as “like dissolves like,” which means that polar molecules will generally dissolve well in polar solvents and non-polar molecules will generally dissolve in non-polar solvents.
Why are alkanes insoluble in water but soluble in organic solvents?
Because alkane molecules are nonpolar, they are insoluble in water, which is a polar solvent, but are soluble in nonpolar and slightly polar solvents. Consequently, alkanes themselves are commonly used as solvents for organic substances of low polarity, such as fats, oils, and waxes.
Why is chlorophyll a more soluble than B?
Chlorophyll b helps in photosynthesis by absorbing light energy. It is more soluble than chlorophyll a in polar solvents because of its carbonyl group.
