Answer:
a) both substances are insoluble in water
b) both substances are soluble in ligroin
c) both substances suffer combustion, octane produces more CO₂ than hexene.
d) both substances are less dense than waterl, with hexene having the lowest density.
e) only hexene would react with bromine
f) only hexene would react with permanganate
Explanation:
a) both substances are non-polar and water is polar
b) both substances are non-polar and lingroin is non-polar
c) C₈H₁₈ + 17.5O₂ → 8CO₂ + 9H₂O
C₆H₁₂ + 9O₂ → 6CO₂ + 6H₂O
d) water = 997 kg/m³
ocatne = 703 kg/m³
hexene = 673 kg/m³
e) bromine test is used to detect unsaturations
f) permanganate test is used to detect unsaturations
Hexene is an unsaturated compound while octane is a saturate compound.
We have to note that the both substances are hydrocarbons and the following will be observed;
a) When water was added to both substances they were found to be insoluble in water.
b) When both substances were dissolved in ligroin, they were both found to be soluble in ligroin.
c) The combustion of both substances produced CO2 but the combustion of octane produced more CO₂ than that of hexene.
d) The both substances are less dense than water, hexene has a lower density than octane.
e) The hexene was found to react with bromine
f) The hexene was found to react with permanganate
