Wilkinson's catalyst is chloridotris(triphenylphosphane)rhodium(I). It is a rouge-colored solid that is soluble in hydrocarbon solvents such as benzene and more so in tetrahydrofuran or chlorinated solvents such as dichloromethane. The compound is widely used as a catalyst for hydrogenation of alkenes. It is named after chemist and Nobel Laureate, Sir Geoffrey Wilkinson, who first popularized its use.

ANSWER

Ethylamine is soluble in water whereas aniline is insoluble in water. Why?

Posted by Pooja Krishnan 8 years, 6 months ago

CBSE > Class 12 > Chemistry

1 answers

Amar Kumar 8 years, 6 months ago

Ethylamine is soluble in water owing to its potential to form intermolecular Hydrogen bonds with water. On the other hand aniline does not undergo hydrogen bonding because of the presence of the benzene which is highly hydrophobic. Therefore aniline is insoluble in water.
