What is meant by terms 'saturated' and 'unsaturated' when applied to alkanes and alkenes? Describe a chemical test to distinguish between the liquids hexane and hexene.

Saturated – contains single bonds only.Unsaturated – contains one or more carbon-carbon double bonds.Shake each with bromine water. Hexene will decolorise bromine water, which will go from orange to colourle...

What are geometrical isomers? Explain, structurally, why geometrical isomers exist.

Molecules differing in the relative bond positions of two groups about carbon-carbon double bonds. Free rotation is not possible about a carbon-carbon double bond. Thus, groups attached to the double-bonded ...

The Nucleophilic substitution mechanism: i. give the mechanism for the reaction between bromoethane and sodium hydroxide solution; ii. explain why the reaction mechanism is called nucleophilic substitution mechanism.

ii. The nucleophile donates a lone pair of electrons to the electrophilic carbon atom in the halogenoalkene. The bromine atom is substituted by the hydroxide ion. The mechanism is accompanied by inversion of...

List the first 4 halogens as they appear in the periodic table as they appear. What does your answer suggest about their relative reactivity?

Fluorine, Chlorine, Bromine, IodineIf you write the electronic structure to start, F = 2,7, Cl = 2, 8, 7, Br = 2, 8, 8, 7, I = 2, 8, 8, 8, 7. This shows that they all have 7 outer electrons so we can tell th...
