Question

2 alkanol gives both haloform and tollen tst. Can it is possible?

Answer 1

Answer:

Explanation:

The compounds which give positive are the one with alpha-methyl groups.  

To be more precise, Ethanal(Acetaldehyde) and methyl ketones.

Ethanal is the only aldehyde which gives a positive iodoform test. Thus, ketone and aldehyde with structure −COCH

​  

 also show positive results.

propan-2-ol is CH  

3

​  

−CH(OH)−CH

​  

 thus it will have −COCH

​  

 group and hence gives a positive iodoform test.
