Because it has 2 double bonds. An ether might not have any double or triple bonds!
This is incorrect. Furan is readily soluble in ether. Furan is partially polar because of its oxygen molecule. Ether is also mildly polar because of its own oxygen.

An important feature that all lipids have in common with one another is they are hydrophobic structures.
Try reacting furan-2-aldehyde with ammonia in ethanol
A substance that does not dissolve is insoluble.
The heteroatom in ether is oxygen.
Insoluble
The lipid glycerol is soluble in both water and ether. Olive oil is soluble in ether, but not water. A solid lipid is insoluble in water, methanol, and ether.
Hi I m confused that in simple furan why it do not show nucleophilic subtitution reaction. while in subtituted furan show it.
The rule states that "like dissolves in like". Since sucrose is a polar covalent compound, it can only dissolve in solvents that are polar. However, petroleum isnt a polar covalent compound, thus compunds that are not covalent will dissolve in it.
Ether has a lower dielectric constant than water. Therefore, the energy required to separate the cations from the anions in ether is greater than in water. The entropy gain that could result from converting solid salt to a solution is therefore not great enough to overcome the attractions between the ions in ether, but it is great enough in water.
Sodium chloride is highly polar (ionic in fact) where hexane is very not. The two don't attract at all, so each is insoluble in the other.
Naphthalene is said to be somewhat soluble in ethyl alcohol (ethanol). It is insoluble in water and very soluble in ether, chloroform, or carbon disulfide.
furan though has a lone pair of electron which is not delocalised but due to high electronegetivity of oxygen it is not a available for donation hence has weak basic proerty
