Group 17- Big daddy Petr

Question 1

True/false, F can have CN of 2, but usually -1 or 0

Answer 1

True

Question 2

What is the only important halogen oxide?

Answer 2

ClO2(does not dimerise at ambient conditions)

Question 3

Why is ClO prefered over Cl2, in bleaching?

Answer 3

Potentially less carcinogenic and does not contain elemental Cl. Made at site, fucking explosive son.

Question 4

5HClO2->4ClO2* + H+ + Cl- + 2H2O what is ClO2? What type of transfer is needed?

Answer 4

Radical

Single electron transfer.

Question 5

What are interhalogens? Give an example? How is it made?

Answer 5

Compounds of halogen elements, from XY, XF3, XF5 and even IF7, very strong ox.
ClF3 is explosive.
Cl2 + 3F2 –> 2ClF3

Question 6

Use of Helium and Ar

Answer 6

Helium super magnets

Ar unreactive in windows.

Question 7

Xe reacts with F to give what?

Answer 7

XenF2n for n=1,2,3 depending on conditions

Strong oxidising agents.

Question 8

Can they be predicted by VSEPR? Are there any that are unsuspecting?

Answer 8

Yep, except XeF82-

Question 9

XeF6 + 3SiO2 –> ?

Answer 9

2XeO3 + 3SiF4

Question 10

KrF2 is made how? Is it stable?

Answer 10

Electrical current at low T, nope haha.
