Which of the following fluoro-compounds is most likely to behave as a Lewis base?
(1) BF3
(2) PF3
(3) CF4
(4) SiF4
Boric acid is an acid because its molecule:
1. | contains replaceable H+ ion. |
2. | gives up a proton. |
3. | accepts OH– from water releasing proton into the solution. |
4. | combines with protons from water molecules. |
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
