  • Answers:
  • Because in AgCl the size of Ag+ ion (cation) is smaller and it can easily fit into interstitial site where as in NaCl the size of Na+ ion is bigger so it cannot fit into interstitial site.

  • Answers:
  • The Wurtz reaction, named after Charles-Adolphe Wurtz, is a coupling reaction in organic chemistry, organometallic chemistry and recently inorganic main group polymers, whereby two alkyl halides are reacted with sodium to form a new carbon-carbon bond.

    Other metals have also been used to effect the Wurtz coupling, among them silver, zinc, iron, activated copper, indium and a mixture of manganese and copper chloride.[

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

  • Answers:
  • 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.

  • Hybridization is the idea that atomic orbitals fuse to form newly hybridized orbitals, which in turn, influences molecular geometry and bonding properties. Hybridization is also an expansion of the valence bond theory
