6 Questions
explain in terms of intermolecular forces why bromine is more soluble in the organic solvent than it is in water
Bromine's primary intermolecular force is dispersion forces. It will preferentially dissolve into the organic solvent because the intermolecular forces with an organic solvent are stronger than intermolecular forces in water
what is the observation for when bromine water is added to 1,1,1-trichloroethane
an orange solution is added to a colourless liquid. Upon addition, the aqueous layer (bottom) turns colourless/fades in colour while organic solvent turns red
Bromine water (orange) was added to both cyclohexane and cyclohexene. Record your observations.
The colours of the liquids swapped (transferred) for cyclohexane. For the cyclohexene, upon shaking, both turned colourless.
why do we shake the test tube upon addition of bromine to the cyclohexane/ene
to increase the SA each substance comes in contact with each other so there can be a faster transfer of substances and mixing
why do alkanes undergo substitution reactions
alkanes are saturated compounds and they already have strong C-C and C-H bonds and each carbon atom is bonded to the maximum number of carbon or hydrogen atoms. So when it reacts, the hydrogen is substituted by another atom or group in the reaction
Why do cis and trans isomers exist for alkenes
due to rigidity of double bond, carbon-carbon double bond in alkenes is restricted
Understand why bromine is more soluble in organic solvents than in water by exploring the role of intermolecular forces in solubility. Learn how the strength of intermolecular forces affects the solubility of a substance. Test your knowledge of chemistry and intermolecular forces.
