Show the steps in the acid-catalyzed formation of a cyclic acetal from

ethylene glycol.

An aliphatic carboxylic acid reacts with an alcohol and the following equilibrium is established RCOOH+R'CH^2OH=RCOOCH^2R'+H^2O what is the number of constituents and the number of components in the system.

An organic compound P, molecular formula CHO, gave two products when heated with concentrated sulphuric acid at 180C, One of these products, R. decolourized an acidified solution of potassium manganate (V11). When P was warmed with acidified potassium dichromate (VI) solution, the organic product formed, M. reacted with sodium carbonate solution to give a colourless gas, N. which turned lime-water 'milky'. Deduce the identity of P. R, M and N explaining your reasoning.

Lamivudine is a drug used for the treatment of HIV (AIDS). This drug stop HIV from infecting cells in the body. Only the (-)-enantiomer of lamivudine is registered for the treatment of HIV because it is more active and less toxic than either the (+)-enantiomer or the racemate. In the (-)-enantiomer, the chiral centre at position 2 has the R configuration and the chiral centre at position 5 has the S configuration. Draw the structure of (-)-lamivudine using hashed and wedged line notions that represents R configuration at 2 and S configuration at 5. Need to show your work-up.
