wat abt hexane ..... wat is d test 4 tat
For hexane, use the 'diffusion' test using Iodine.
In a test tube, put some Hexane and Aqeous Iodine. The Iodine is non-polar whereas Hexane is polar.So they are immiscible; Moreover Iodine is reddish brown (aqeous) but forms a purple layer layer with hexane as it diffuses
2nd test:
Combustion - Alkanes burn to give Co2 + H2O
3rd test:
Alkane or alkene?!
Use bromine in a absence of uv --> Alkane (Hexane) stays same Alkene (Hexene) decolorises
