- Rank the basicity of the following sets of compounds. And give explanation.Rank the acidity of each of these compounds from least to most acidic. The explicitly drawn Hydrogens should be compared. What would be a small explanation as to why they are ranked in that order?(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) Ph THF A Ph Ph B H₂SO4 100 °C 3 OH (iii) In analysing both these methods, are there other possible alkene products other than methylenecyclohexane 2? Use mechanistic details to support your answer.
- Put the following set of compounds in the increasing order of their acidity. Explain the reason why.Interpret the acidity of alcohols on the basis of ground-state polarization and stability of the alcoholate anion(indicate and give symbols for bond polarization)! Compare the relative acidity of ethanol and 2-fluoroethanol!Rank the molecules in decreasing (strongest to weakest) acidity. Include ALL resonance structures with arrows and explain reasoning for rank.
