- (c) Arrange the following compounds in order of increasing acidity, and explain the reasons for your choice of order: phenol, cyclohexanol, 2-fluorocyclohexanol, 2-fluorophenol.arrow_forward(a) Rank the following compounds in order of increasing acidity. (b) Which compound forms the strongest conjugate base?arrow_forwardArrange each group of compounds in order of increasing acidity.(a) phenol, ethanol, acetic acidarrow_forward
- Arrange the following compounds in the increasing order of their acid strength: p-cresol, p-nitrophenol, phenolarrow_forwardGive reasons for the following :(i) Phenol is more acidic than methanol.(ii) The C—O—H bond angle in alcohols is slightly less than the tetrahedral angle (190°28′).(iii) (CH3)3C—O—CH3 on reaction with HI gives (CH3)3C—I and CH3—OH as the main products and not (CH3)3C—OH and CH3—I.arrow_forwardSuppose you have a mixture of these three compounds. Devise a chemical procedure based on their relative acidity or basicity to separate and isolate each in pure form.arrow_forward
- If the G for a reaction is 4.5 kcal/mol at 298 K, what is the Keq for this reaction? What is the change in entropy of this reaction if H = 3.2 kcal/mol?arrow_forwardPredict the major product when each reagent reacts with ethylene oxide.(a) NaOCH2CH3 (sodium ethoxide) (b) NaNH2 (sodium amide)arrow_forward(a) Tsomane and Nyiko were given a task of synthesising methylenecyclohexane 2. After a brief discussion with each other, Tsomane proposed Method A to synthesise 2 from cyclohexanone 1 while Nyiko proposed Method B that started from hydroxymethylcyclohexane 3. Each student believed that their proposed method is better than the other. (Scheme below) (1) Ph Ph 836 Ph THF A 1 B H₂SO4 100 °C 3 OH Which of the two methods (A or B) is more likely give high yield of methylenecyclohexane 2? Briefly explain.arrow_forward
- Which is the stronger acid in each of the following pairs? Explain your reasoning. (a) Phenol or p-hydroxybenzaldehyde (b) m-Cyanophenol or p-cyanophenol (c) o-Fluorophenol or p-fluorophenolarrow_forwardNow that you have learned about solubility, explain why aspirin (Section 2.7) crosses a cell membrane as a neutral carboxylic acid rather than an ionic conjugate base.arrow_forwardRank each set of compounds in order of increasing basicity.(a) NaOH, NH3, CH3NH2, Ph¬NH2 (arrow_forward
