The correct order of acid character of the following compounds is:
| (I) | (II) | (III) | (IV) |
| 1. | III > II > I > IV | 2. | IV > III > II > I |
| 3. | I > II > III > IV | 4. | II > III > IV > I |
| 1. | c > d > a > b | 2. | b > a > d > c |
| 3. | a > b > c > d | 4. | b > c > a > d |
The final product 'C' of the following sequence of reactions is:
| 1. | \(\mathrm{CH_2-COOH\\ |\\ CH_2-COOH}\) | 2. | \(\mathrm{CH_2-Br\\ |\\ CH_2-Br}\) |
| 3. | \(\mathrm{CH_2-COOH\\ |\\ CH_2-CN}\) | 4. | \(\mathrm{CH_2-CN\\ |\\ CH_2-CN}\) |

The reaction scheme below shows some reaction conversions of organic molecules.

Which is the correct combination of processes and compounds for this scheme?
| 1. | process T: reduction; compound W: ester; compound X: amide |
| 2. | process T: reduction; compound W: ketone; compound X: nitrile |
| 3. | process T: oxidation; compound W: ester; compound X: amide |
| 4. | process T: reduction; compound W: ketone; compound X: amide |
The compound formed as a result of oxidation of propyl benzene by KMnO4 is –
1. benzophenone
2. acetophenone
3. benzoic acid
4. benzyl alcohol
| 1. | B > A > D > C |
| 2. | B > D > C > A |
| 3. | A > B > C > D |
| 4. | A > C > B > D |
Benzoic acid gives benzene on being heated with X and phenol gives benzene on being heated with Y. Therefore, X and Y are respectively
1. Sodalime and copper
2. Zn dust and NaOH
3. Cu and sodalime
4. Sodalime and zinc dust
