Hydrocarbons

Conclusion: In conclusion, it was been discover that unknown#1.20 is the evocative hydrocarbon, methylbenzene. During the portal of blood cellic number 35, it was expected that no reception would occur simply by adding an paraffin series (cyclohexane) to the bromine bring outcome. For an alkane to match with bromine an additional source of light needfully to be provided. This was observed when cyclohexane and bromine turned a stern orange color, meaning no reaction took place to decolourize bromine. Alkenes and aromatics argon more reactive( because of their pi bonds) hence when bromine solution was added to these hydrocarbons, it was expected for reactions to take place. Cyclohexene, toluene and the unknown hydrocarbon both decolorized bromine which is what we inferred. This means the unknown#1.20 is totally(prenominal) an alkene or an aromatic compound. Acid permanganate should react with anything unsaturated, wherefore non react with alkanes such as cyclohexane as was seen. Alkenes go out react with paneling permanganate to name vicinal diols while aromatics atomic number 18 quite difficult to react with acid permanganate (difficult to oxidize) so no reaction should happen. In the examples, cyclohexene reacted and organise two layers. Toluene so far remained in a involved solution with the acid permanganate bemuse to the bottom in a small ball(no reaction).

The unknown in addition did not react with the acid permanganate. It looked the exact same as toluene and acid permanganate which narrows it down to an aromatic! Hydrocarbons are non-polar molecules, where as irrigate is a polar molecule consequently we did not expect any of the hydrocarbons to be dissoluble in water except for acetone. dimethyl ketone should be water soluble since it has a double bonded oxygen atom that produces a polarization which allow cause it to dissolve in water. As expected, cyclohexane, cyclohexene, and toluene were all insoluble due to the ceremonial of beading(cyclohexane and cyclohexene) and formation of two layers(toluene). propanone was concluded to be soluble since...If you want to get a full essay, order it on our website: Ordercustompaper.com
