PAPER ONE: MULTIPLE CHOICE QUESTIONS Acetylsalicyclic acid commonly called aspirin is a drug widely used in Cameroon. Its structure is 5. TYPE ONE QUESTIONS Questions 1 - 49 For questions 1-9 choose the letter A-D of the INCORRECT altemative -OH 1. Carboxylic acids can be prepared by the A) oxidation of its corresponding primary Aspirin can be said to contain the. alcohol using acidified potassium dichromate. A. Ester functional group B. Acid functional group C. Benzene ring functional group D. Anhydride functional group B) oxidation of a tertiary alcohol with potassium permanganate Vil acidiefied C) hydrolysis of a nitrile on boiling with either dilute acid or alkali D) oxidation of aldehydres with acidified During the reaction of ethanol and ethanoic acid A. 6. the ethanol and ethanoic acıd are mixed in equimolar the reaction takes place potassium dichromate room 2. In the reaction CH,COOH CH,OH CH,COOC,H, + H,O A) the rate of the reaction is slow at room temperature C. the reaction is a condensation D. hydrogen ions are added temperature B) the equilibrium can be shifted in favour of the ester when water in removed The alkali hydrolysis of an C,H, O, can produce CH COOH + CH,(CH ),OH B. 7. A. C) it is the OH group of the alcohol that is is called saponification can produce CH,CH,COONA + CH (CH,),CH,OH can produce CH,CH,CH COO- + CH,CH,CH,OH lost as water. C. D) it is the OH group of the acid that is lost as water. D. 3. All the compounds below can be reduced by lithium aluminum hydride in other 8. This question relates to the oxidation of
