Question

1, (For the known compound, 2-propanol, predict whether there will be a positive or negative result for each of the following three tests:

Dichromate
Iodoform
2, 4 dinitrophenolhydrazine test

2, For the known compound, t-butanol, predict whether there will be a positive or negative result for each of the following three tests:

2, 4 dinitrophenolhydrazine test
Iodoform
Dichromate

Answer 1

2-Propanol will give:

           Positive Dichromate Test. (Easily Oxidizable group)

           Positive Iodoform Test (Oxidized into Keto-Methyl Group)

           Negative 2,4-DNP Test.

^t-Butanol will give:

           Negative Dichromate Test. (No Easily Oxidizable group)

           Negative Iodoform Test (Can not be oxidized into Keto-Methyl Group)

           Negative 2,4-DNP Test.
