- (a) Draw the structures of the following compounds :(i) 4-Chloropentan-2-one (ii) p-Nitropropiophenone(b) Give tests to distinguish between the following pairs of compounds :(i) Ethanal and Propanal (ii) Phenol and Benzoic acid(iii) Benzaldehyde and Acetophenonearrow_forwardNucleophilic aromatic substitution provides one of the common methods for making phenols. Show how you would synthesize the following phenols, using benzene or toluene as your aromatic starting material, and explain why mixtures of products would be obtained in some cases.(a) p-nitrophenol (b) 2,4,6-tribromophenol (c) p-chlorophenolarrow_forwardProvide the reagents and solvents (where appropriate) needed to bring about the following transformations. (a) CI (b)arrow_forward
- Develop syntheses for the following compounds. As starting materials, you may use cyclopentanol, alcohols containing no more than four carbon atoms, and any common reagents and solvents. (a) trans-cyclopentane-1,2-diol (b) 1-chloro-1-ethylcyclopentanearrow_forward(a) Compound A is an optically active alcohol. Treatment with chromic acid converts A into a ketone, B. In a separate reaction, A is treated with PBR3, converting A into compound C. Compound C is purified, and then it is allowed to react with magnesium in ether to give a Grignard reagent, D. Compound B is added to the resulting solution of the Grignard reagent. After hydrolysis of the initial product (E), this solution is found to contain 3,4-dimethylhexan-3-ol. Propose structures for compounds A, B, C, D, and E.arrow_forward(a) Give chemical tests to distinguish between the following pairs of compounds :(i) Benzoic acid and Phenol (ii) Benzaldehyde and Acetophenone(b) An organic compound with molecular formula C5H10O does not reduce Tollen’s reagent but forms an addition compound with sodium hydrogen sulphite and gives a positive iodoform test. On vigorous oxidation, it gives ethanoic acid and propanoic acid. Identify the compound and write all chemical equations for the reactions.arrow_forward
- Explain the following statements. You must use chemical equations to justify your explanation. (ii) (I) Phenol is more acidic than cyclohexanol.arrow_forwardShow, by writing an appropriate series of equations, how you could prepare propyne from each of the following compounds as starting materials. You may use any necessary organic or inorganic reagents. (a) 2-Propanol (d) 1,1-Dichloroethane (b) 1-Propanol (e) Ethyl alcohol (c) Isopropyl bromidearrow_forwardDescribe how would you distinguish the following pairs, (a) Benzene and cyclohexane (b) Phenol and toluene (c) Phenol and benzoic acidarrow_forward
- Triphenylmethanol is insoluble in water, but when it is treated with concentrated sulfuric acid, a bright yellow solution results. As this yellow solution is diluted with water, its color disappears and a precipitate of triphenylmethanol reappears. Suggest a structure for the bright yellow species, and explain this unusual behavior.arrow_forward(c) Answer each of the questions below that relate to acetophenone: Xo (i) (ii) (iii) Draw the structure of the enol form of acetophenone. Give a stepwise mechanism for the conversion of acetophenone into its enol form. Show how each of the three compounds A, B and C below can be prepared from acetophenone. Explain clearly what reactants/reagents would be required in each case. odocor A B Br Carrow_forwardThe odor of ripe bananas and many other fruits is due to the presence of esters. For example: Banana oil (isopentyl acetate) (a) Write the name (common or IUPAC) of the ester responsible for the fragrance of the following: pineapple, orange, apple, peach, & lavender (b) Choose one fragrant from (a) and name the alcohol and the carboxylic acid needed to synthesize this ester. (c) Show the detailed mechanism of the Fischer Esterification reaction that will be involved in the synthesis of the fragrant you have chosen in part (a).arrow_forward
