A) \[5.65\times {{10}^{-10}}\]
B) \[6.50\times {{10}^{-12}}\]
C) \[5.65\times {{10}^{-13}}\]
D) \[5.65\times {{10}^{-12}}\]
Correct Answer: A
Solution :
| [a] Key Idea Element having higher tendency to get reduced or to accept an electron is strong oxidising agent. |
| Fluorine is the most electronegative element because electro negativity decreases on moving down the group. Hence it gets reduced readily into \[{{[Cr{{(N{{H}_{3}})}_{6}}]}^{2+}}\]ion and is a strongest oxidising agent. |
