Course Overview: Group-13 Elements| Boron Family

This lesson will discuss the physical nature, Electronic Configuration and the anomalous Behaviour of Boron.

Introduction to Boron Family

This lesson will discuss the unusual trend in melting point and atomic size of Group-13 Elements ie. Boron Family. 
Why Barium has abnormally high melting point? 
Why the Galium Thermometers are used?

Physical Properties: Melting Point and Atomic Size of Boron Family

This lesson will discuss the abnormal trend in the Atomic size and Ionisation Enthalpy of Boron Family. 

Why the Galium has higher Ionisation energy than that of Aluminum?

Physical Properties: Ionisation Enthalpy in Boron Family

This lesson will discuss the oxidation state and their stability in Boron Family.

Boron form covalent compounds not ionic. Why ?

Physical Properties: Oxidation State and Their Stability in Boron Family

This lesson will discuss the covalent nature of trihalides of boron and their relative Lewis acid character.

Halides of Boron and Their Relative Lewis Acid Character (Part-1)

This is the continued part of previous lesson where we will learn about the relative Lewis acid character in Boron halides and why the BF3 molecule does not undergo hydrolysis while BCl3 and BBr3 get easily hydrolysed?

Halides of Boron and Their Relative Lewis Acid Character (Part-2)

This lesson will discuss the halides of Al , Ga, In, Tl and thier relative Lewis Acid character. 
Why Aluminium chloride exist as a dimer while Boron trichloride exist as a monomer?

Other Halides of Group-13 Elements

This lesson will discuss the Hydrides of Group- 13 elements and the structure of Diborane ie. B2H6 molecule, describing the concept of multicentered bonding. 
Q/A covered:
1. Why BX3 are well known but BH3 is not known ? 
2. Why the methylation in B2H6 molecule occur at terminal H's only?

Hydrides & the structure of Diborane (B2H6)

This lesson will discuss the reactivity of Group- 13 elements towards air, water, acids, alkali's and Halogens.

Also learn about the Oxides and hydroxides of Boron Family and their acidic / basic behaviour.

Chemical Properties/ Reactivity of Group-13 Elements

This lesson will discuss the occurrence of Boron in the combined form, methods of extraction of 'B' and it's  properties.

Chemistry of Boron

This lesson will discuss the chemistry of Boron trioxide, it's preparation and it's properties.

Boron trioxide: B2O3

This lesson will discuss the methods of preparation of Boric acid. 

1. Why B(OH)3 is a weak Lewis acid ? 
2. Hydrolysis of Boric acid: 
3. Why the organic polyhydroxy compounds are added to determine it's end point during titration? 
4. Action of heat and HF on B(OH)3
5. Structure of Boric acid and it's uses.
6. Test for Borate radical.

Boric Acid: B(OH)3

This lesson will discuss the concept of Multicentered bonding in  B2H6, Al2Cl6 and Al2Me6 molecules thoroughly. 
This will explain the fact that why B2H6 is a Lewis acid while Al2Cl6 is not? 
What is the the hybridisation of B atom in B2H6 and why? 
What is 3c-2e- and 3c- 4e-bond?

Multicentered Bonding in B2H6, Al2Cl6, Al2Me6 etc.

This lesson will discuss the preparation of Borax, it's properties, Borax bead test and  how this test helps in the identification of metal ion and the most important structure of Borax.

Borax: Na2B4O7.10H2O

This lesson will discuss the chemistry involved in Diborane with it's preparation and some important properties. 
Few questions are given on one of the important property Nucleophillic Substitution Reaction on Diboranes.

Diborane: B2H6

This is the continued part of previous lesson where I have discussed the questions given on Nucleophilic substitution reaction on Diborane and other properties.

Diborane: B2H6 (part-2)

This lesson will discuss the chemistry of Aluminum, action of air , water, acids and alkali's on Al , it's uses and the compounds of Aluminum ie. Al2O3, AlCl3, Alums.

Chemistry of Aluminum

This lesson will discuss the preparation and properties of Aluminum oxide (Al3O3) and Aluminum chloride (AlCl3)

Compounds of Aluminum: Al2O3, AlCl3

This lesson will discuss about double salts or alums.
Answer the following questions: 
1. Anhydrous AlCl3 cannot be prepared by heating it's hydrated salt.Why?
2. What will happen if Aluminum is heated with coke in an atmosphere of nitrogen ?

Compounds of Aluminium: Alum
