Question

Please answer all 4 questions

1) Draw condensed structure formulas for the following compounds

2) How would you describe the difference between saturated and unsaturated hydrocarbons and what is a distinguishing feature of aromatic hydrocarbons?

5) Do you expect the aromatic hydrocarbons to react in a similar way to the cyclic alkenes, since they are both cyclic compounds and have a double bond? explain

6) write the structure of the product. if no reaction occurs write NR

Final questions 1. Draw condensed structure formulas for the following compounds. cyclohexane cyclohexene toluene 2. How would you describe the difference between saturated and unsaturated hydrocarbons and what is a distinguishing feature of aromatic hydrocarbons?

2.) The colour of bromine water is brown. With bromine water saturated compounds do not decolourise bromine water.With bromine water unsaturated compounds decolourises the bromine water.while Aromatic compound burns with sootyflame

5.) Aromatic Hydrocarbon consists of typically a Benzene ring or multiple Benzene rings bonded together, which means that it is 6 Carbons bonded in a cyclic (ring) structure with alternating double bonds. I.e single bond, double bond, single bond etc.

Cycloalkanes on the other hand as depicted in the name "alkane" consist of a cyclic structure with n (n = 1,2,3,4...) number of Carbon atoms but only have single bonds between the Carbons.

This results in many differences in chemical reactivity of both types of compounds: Aromatics give electrophillic substitution reactions where as cycloalkane gives addition , substitution and many more reactions.
