Concept introduction:
Lewis acids are electron pair acceptors.
Lewis bases are electron pair donors.
Any electron deficient species can act as a Lewis acid such as compounds containing group IIIA elements like Boron or Aluminum.
Compounds having vacant orbitals also act as Lewis acids like halides of Iron, Zinc and Aluminum.
Electron loving or seeking compounds are called Electrophiles.
All Lewis acids are electrophiles but all electrophiles are not Lewis acids
Electron donating compounds are called Nucleophiles.

- 3. How would you separate these to compounds using acid-base chemistry? (a) Identify all functional groups; and (b) Draw a flow diagram of your separation process. H3N HOarrow_forwardEthanamine, CH,CH;NH2, is a weak base. pKa(CH;CH2NH3') = 10.6 (a) (i) Write an equation to show the reaction of ethanamine. CH;CH;NH2 with water. (ii) Explain, with reference to equation and the species in solution, what is mean be the terms weak and base.arrow_forwardI attached the problem for this question.arrow_forward
- How do triphenylphosphine and borane form a Lewis acid-base adduct? (a) The phosphorus atom in triphenylphosphine is less electronegative than the boron atom in borane and is thus attracted to boron to form the bond. (b) The phosphorus in triphenylphosphine exchanges with the boron from borane. (c) Triphenylphosphine donates the lone pair on its phosphorus to the electron-deficient boron in borane. (d) Triphenylphosphine donates a phenyl ring from its phosphorus to the electron-deficient boron in borane. (e) The phosphorus in triphenylphosphine accepts a proton from the proton-rich borane.arrow_forwardGive detailed Solution with explanation needed..don't give Handwritten answerarrow_forwardGive clear detailed Solution with explanation needed..don't give Handwritten answerarrow_forward
