Q. No.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 |
Reason(R): +l effect of CH3 makes the acetic acid weaker.
1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is a true statement but R is false.
4. Both A and R are false statements.

The compound formed as a result of oxidation of propyl benzene by KMnO4 is –
1. benzophenone
2. acetophenone
3. benzoic acid
4. benzyl alcohol
A: Trichloroacetic acid
B: Trifluoroacetic acid
C: Acetic acid
D: Formic acid
The correct order of decreasing acid strength of the above-given acids is:
| 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
