  1. Chunk 2 By Eashwarran and Sachin

  2. - understand the electron deficient nature of Group 3 systems such as BF3, BCl3, AlCl3 and their electron acceptor properties, considering their structures B only has 6 electrons in outer shell - So it is deficient in a pair of electrons (similar in BCl3 and AlCl3)

  3. - understand the electron deficient nature of Group 3 systems such as BF3, BCl3, AlCl3 and their electron acceptor properties, considering their structures AlCl3: Acts as a catalyst in the Friedel-Crafts reaction of benzene- electrophilic substitution reactions of benzene

  4. - understand the electron deficient nature of Group 3 systems such as BF3, BCl3, AlCl3 and their electron acceptor properties, considering their structures AlCl3: Acts as a catalyst in the chlorination reaction of benzene - electrophilic substitution reactions of benzene

  5. - Explain the ready formation of Al2Cl6 dimer, its structure and its bonding Two AlCl3 molecules can join to generate to form Al2Cl6 Because Al is deficient in a pair of electrons Both Al atoms form a DATIVE COVALENT BOND Al2Cl6 ↔ 2AlCl3 reactions moves towards the right above 200°C

  6. - Understand the formation of donor-acceptor compounds such as NH3.BF3 NH3 and BF3 join together to form NH3BH3 A DATIVE COVALENT BOND forms
