This presentation discusses interhalogens and pseudo halogens. It is presented by a group consisting of 5 members: Ayesha Arshad, Khadija Akram, Adsa Khalid, Maryam Sarfraz, and Sana Naseem. The presentation covers the topics of interhalogens and pseudo halogens. Interhalogens are binary covalent compounds formed when halogens combine with other halogens. There are four types of interhalogens: AB, AB3, AB5, and AB7, which differ in their composition and structures. Pseudo halogens are similar to halogens in that they react with alkalis, form dimer compounds, show properties of addition compounds
Interhalogens pseudohalogens
- 1. PRESENTATIO N GROUP MEMBERS 1. Ayesha Arshad 2. Khadija Akram 3. Adsa Khalid 4. Maryam Sarfraz 5. Sana Naseem 1
- 3. InterHalogens : Halogen combine with other halogen atom to form binary covalent compounds called Interhalogens 3
- 4. Features of INTERHALOGENS : They are most Electronegative AB type compounds ( AB,AB3,AB5, AB7) are present. A is less Electronegative than B A never F because ( F have high electronegative value and never show +ve oxidation state ) Central Atom has large Atomic Number If Greater Electronegativity Difference Than greater will be the No of bonds formed 4
- 5. Types : There are four types of Interhalogens which are : 1 AB type Interhalogens 2 AB3 type Interhalogens 3 AB5 type Interhalogens 4 AB7 type Interhalogens 5
- 6. AB type : Example : ICL is the example of AB type Interhalogens. Preparation : It is prepared by adding Iodine to liquid Chlorine and keeping the mixture at 30 to 35 temperatures for 24 hours I2 + Cl2 2ICL 6
- 7. AB type : 7
- 8. Properties and Structure : 8
- 9. AB3 Type Interhalogen : 9
- 10. Properties of AB3 : 10
- 11. Structure of AB3 ( ICI3 ) : 11
- 12. AB5 Type : 12
- 13. Structure of AB5 ( IF5 ) : 13
- 14. AB7 Type : 14
- 17. Preparation of Pseudo Halogens : 17
- 18. PROPERTIES: Similarities Between Pseudo halogen And Halogens: Both react with Alkalis. Both form Dimer Compounds. Both shows properties of Addition compounds. Both form complex with Transition metals. 18
