Select the corect statement(s) below 1 Benzene is produced when sodium berzoate is heated with soda lime 2 Benzene carboxylic acid is prepared by the acid hydrolysis of benzonitrie, 3 Benzene carboxylic acid is prepared by the alkaili hydrolysis of benzonitrde. 85 87 CH CH(On)GOH Can be prepared by the oxidation of propanal 2. is an optical inactive hydroxyl acid 3. is prepared by the a- chlorination followed by alkali hydrolysis of propanoic acid. 66. Which of the foliowing reaction(s) of 88. Benzoic acid carboxylic acids exhibits their acidic property. 1. 2RCO,H+Mg(s(RCO,,Mg 1. gives a buf precipitate with neutral iron(Il) chloride evolves carbondioxide when sodium hydrocarbonate is added to it 3. bums with a luminous sooty flame 2. 2 2RCO H Na co.(s) 2RCO.Na(aq) + CO (g) + H,O(1) RCO H +NaOH RCO Na(aq) + H,O) (6)H+ 3. TYPE FOUR QUESTIONS Questions 89-102 DIRECTIONS: Each of the following questions consist of a statement in the left hand columri followed by a second statement in the right hand column. Decide whether first statoment is tru or false. Deide wether the second statement is true or false Then choose A. f both statements ere true and the second statement is the CORRECT explanation of the first statement. B. If both statements are true and the second statement is NOT a correct expiaration ca the first statement. C If the first statement is true, but the second statement is false. D. If the first statement is falso, but the second statement is true. DIRECTIONS SUMMARISED SECOND STATEMENT TRUE TRUE FALSE TRUE FIRST STATEMENT A. Second statement is a CORRECT explanation of the first Second statement is NOT a correct explanation of the first. TRUE TRUE C TRUE D. FALSE SECOND STATEMENT FIRST STATEMENT Carboxylic acids contain the carbonyl functional group 89, Aliphatic carboxylic acids form a homologous series of general molecular formula C H CcO.H 90 Carboxylic acids act as Lewis bases in their reaction with phosphorus trichloride An acid chloride is formed when carboxylic acids react with phosphorus trichloride 91 2-hydroxybenzoic has a lower bolling point than 4-hydroxybenzoic acid. Intra molecular hydrogen bonds exist in 2-hydroxy benzoic acid while inter molecular hydrogen bonds are found in 4-hydroxybenzoid acid 359
