Given pK a values are to be matched with the given structures. Concept introduction: The strength of an acid is its tendency to donate a proton. The strength of an acid is described by its pK a value. The lower the pK a value, the stronger is the acid. Acid strength depends on the number of electronegative atoms near the acidic proton. Down the group, the electronegativity for halogens decreases from top to bottom. Anions are stabilized by electron withdrawing groups near the negative charge. The strength of an acid depends on the stability of its conjugate base. The stronger acid has more stable conjugate base.

но HO но он The pK, of ascorbic acid (vitamin C) is 4.17, showing that it is slightly more acidic than acetic acid (CH3CO0H, pKa 4.74). (a) Show the fou r different conjugate bases that would be formed by deprotonation of the four different OH groups in ascorbic acid. (b) Compare the stabilities of these four conjugate bases, and predict which OH group of ascorbic acid is the most acidic. (c) Compare the most stable conjugate base of ascorbic acid with the conjugate base of acetic acid, and suggest why these two compounds have similar acidities, even though ascorbic acid lacks the carboxylic acid (COOH) group.

(a) Explain how NaBH, in CH;OH can reduce hemiacetal A to 1,4-butanediol (HOCH,CH,CH,CH,OH). (b) What product is formed when A is treated with Ph;P=CHCH,CH(CH),? (c) The drug isotretinoin is formed by reaction of X and Y. What is the structure of isotretinoin? Although isotretinoin (trade name Accutane or Roaccutane) is used for the treatment of severe acne, it is dispensed under strict controls because it also causes birth defects.

(i) Draw the dissociation reaction for a carboxylic acid in water and define the Ka for this reaction. Write the equation that relates pKa to Ka. (ii) A deprotonated carboxylic acid can be drawn in two resonance forms. Draw the two forms and explain what the term “resonance” means. (iii) Draw an energy profile for the above dissociation reaction and describe how the profiles for a strong and a weak acid would differ.
