What is the chemical test to distinguish between ethanol and propanol?

Answer 1

You can eliminate ethylbenzene but you cannot eliminate methylbenzene to form an unsaturated carbon. Then, you can use liquid bromine in absence of UV rays to test for C=C bond. Benzylethene would decolourize Br(l) while ethylbenzene will not.

Answer 2

Ethene is an unsaturated substance since it is alkene and has one double bond, we can use bromine water to test ethene. Yellow bromine water turns colourless if the substance is ethene. If it is methane which is alkane ( not alkene ), bromine will stay yellow.

Answer 3

By oxidation, both will decolourise KMnO4. In addition, there will be evolution of CO2 gas from methanal which would give a white precipitate in limewater. The presence of CO2 from oxidation of methanal will help to differentiate between methanal and ethanal.

Hope this helps!! Cheers.

Answer 4

You could chemically differentiate between methane and ethene by treating them with Ozone and Hydrogen Peroxide. This would cleave the double bond in ethene to form two carboxylic acids, but would make water and O2 with methane.

Answer 5

Use acidified KMnO4, heat

Both forms benzoic acid but ethyl benzene forms CO2 which u can test with limewater

Answer 6

You have to prestige 20 times, then perhaps buy Halo 4 on the day it comes out.

Answer 7

Ethane is a single bond atom and and ethene is a doble bond atom

Ethane is unsaturated , meaning its a single bond and ethene is saturated .

Answer 8

Me personally, if I knew it was one or the other, I'd measure the boiling point as the easiest test if I didn't have an NMR spectrometer handy.

Answer 9

Si9nce they are both colourless liquids - you would have to do chemical testing to distinguish which substance was which.
