Question

Does 1,1,1-trichloroethane or methyl chloroform dissolve Cl2, Br2 and I2? If so, will the solution show different color? like for Cl2 colorless,Br2 brown and I2 purple?

Answer 1

\[CH_{3}CHCl_2 + Cl_2 → CH_{3}CCl_3 + HCl\]

I2 is deep purple color. Br2 is a reddish brown, Cl2 is a green. F2 is yellow.

So green coloured Cl2 turn colourless on reacting with methyl chloroform

Answer 2

The relative oxidizing ability of halogens corresponds to their order in the Periodic Table, F2 > Cl2 > Br2 > I2

I am not sure whether Br2 and I2 react with methyl chloroform

Answer 3

In my book, there is an experiment of mixing Br and KI to form Kbr and I2 through redox reaction, and the 1,1,1-trichloroethane is used to test the presence of halogen.
It state that there will be 2 layer of solution form in the test tube(I guess it is 1 layer of salt solution(KBr) and another layer of 1,1,1-trichloroethane with brow color indicate the presence of I2). What i don understand is y does the color of 1,1,1-trichloroethane change to purple when I2 is form. Does this mean I2 produce and dissolve in 1,1,1-trichloroethane and turn it purple?

Answer 4

Yes, I2 is purple in colour and soluble in 1,1,1-trichloroethane => turn colourless KI to purple I2 dissolved in 1,1,1-trichloroethane

Answer 5

Covalent compounds are usually soluble in organic solvent like 1,1,1-trichloroethane

Answer 6

So it is L2 cause the 1,1,1-trichloroethane look purple?

Answer 7

Yes :)

Answer 8

Actually I2 causes purple colour
