Among the following, the correct order of acidity is:
1. HClO < HClO2 < HClO3 < HClO4
2. HClO2 < HClO < HClO3 < HClO4
3. HClO4 < HClO2 < HClO < HClO3
4. HClO3 < HClO4 < HClO2 < HClO
X and Y in the above-mentioned reaction are respectively:
1. X = 2–Butyne; Y = 3–Hexyne
2. X = 2-Butyne; Y = 2-Hexyne
3. X = 1-Butyne; Y = 2-Hexyne
4. X = 1-Butyne; Y = 3–Hexyne
At room temperature, MY and NY3, two nearly insoluble salts, have the same Ksp values of 6.2 × 10-13. The true statement regarding MY and NY3 is:
| 1. | The molar solubility of MY in water is less than that of NY3. |
| 2. | The salts MY and NY3 are more soluble in 0.5 M KY than in pure water. |
| 3. | The addition of the salt of KY to a solution of MY and NY3 will have no effect on their solubilities. |
| 4. | The molar solubilities of MY and NY3 in water are identical. |
Consider the nitration of benzene using mixed conc. H2SO4 and HNO3.
If a large amount of KHSO4 is added to the mixture, the rate of nitration will be:
| 1. | Slower | 2. | Unchanged |
| 3. | Doubled | 4. | Faster |
The product formed by the reaction of an aldehyde with a primary amine is:
1. Ketone
2. Carboxylic acid
3. Aromatic acid
4. Schiff base
The pressure of H2 required to make the potential of H2 - electrode zero in pure water at 298 K is:
