TASK 3 ( Mechanism & Predict Structure)

1	Dehydration of 2-methylcyclohexanol with concentrated sulphuric acid yields a mixture of three alkenes. Draw all the structure of alkenes and suggest the major product . Propose the mechanism of its formation
2	Two organic compounds, A and B have a similar molecular formula, C4H9Cl. Both compounds react with sodium hydroxide aqueous solution to form C and D with molecular formula C4H10Cl via SN1 and SN2 mechanisms respectively. Draw the structure of A, B, C and D. Write a mechanism for the formation of D.
3	Chlorination of benzene is different from the chlorination of methane. a) State the type of reaction for chlorination of benzene. b) Write the mechanism.
4	A few organic compounds represented by the  letters P to S are shown below:             Which of the above compounds will;             a) form an ester when it reacts with ethanol?             b) decolorised hot acidified KMnO4?             c) form silver mirror when it reacts with Tollen's reagent?
5	Both P (C2H4O) and Q (C2H6O) react similarly with an alkaline iodine solution. But only P can      react with 2,4 DNPH to produce yellow precipitate.     a) Identify P & Q. Explain     b) Write the chemical equations for the above reactions
6	When compound S (C4H10O) is reacted with acidified KmnO4, compound T is obtained. Reaction of S with concentrated H2SO4 yields hydrocarbon U (C4H8). Compound U reacts with dilute H2SO4 to produce compound W (C4H10O). Compound W does not react with acidified KMnO4 and its is an isomer of compound S. Determine the structural formula of S, T, U and W.
7	An ester C4H8O2 produces carboxylic acid A, C3H6O2 and alcohol B, CH4O. Alcohol B reacts with PBr3 to yield alkyl halide C. When treated with KCN followed by hydrolysis (acid), this halides produces carboxylic acid D which contain less one carbon atom than the above acid. Deduce the structures of ester, compound A, B, C & D. Write all chemical equation for the reaction involved.
