Sample questions
-
1.Which test would best distinguish pentan-2-one from pentan-3-one?
- A.Iodoform test: only pentan-2-one (a methyl ketone) gives a yellow precipitate
- B.Tollens' test: only pentan-3-one responds
- C.Fehling's test: only pentan-2-one responds
- D.2,4-DNP test: only pentan-3-one reacts
-
2.Which two-step sequence best converts toluene to benzoic acid?
- A.Vigorous oxidation with hot alkaline KMnO4, then acidification
- B.Rosenmund reduction, then hydrolysis
- C.DIBAL-H, then water
- D.Friedel-Crafts acylation, then NaBH4
-
3.The common name of dimethyl ketone (CH3COCH3) is:
- A.Acetone
- B.Acetaldehyde
- C.Acetophenone
- D.Formaldehyde
-
4.Assertion (A): Aldehydes are oxidised by Tollens reagent and Fehlings reagent, whereas ketones are not. Reason (R): Mild oxidising agents such as Tollens and Fehlings reagents are used to distinguish aldehydes from ketones.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
5.Assertion (A): Carboxylic acids liberate carbon dioxide on treatment with sodium carbonate or sodium hydrogencarbonate, whereas phenols do not. Reason (R): Carboxylic acids react with weaker bases such as carbonates and hydrogencarbonates, unlike phenols.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
