Which of the following pairs of transition metal ions is the strongest oxidizing agent?

Electrical disintegration or Bredig's Arc method involves

Answer the question on the basis of passage given below :
Nitrogen differs from rest of the members of group 15 due to its small size, high electronegativity, high ionization enthalpy and non-availability of d orbitals. Nitrogen has unique ability to form pa - pa multiple bonds with itself and with other elements having small size and high electronegativity. Heavier elements of this group do not form pa - pr bonds as their atomic orbitals are so large and diffuse that they cannot have effective overlapping.
Arrange the following in decreasing order of their basic strength :
A. PH3 \(_3\)
B. \(AsH _3\)
C. \(NH _3\)
D. \(SbH _3\)
E. \(BiH _3\)
Choose the correct answer from the options given below:

Un-decomposed silver bromide from developed film, in black and white photography, makes a complex with hypo. The formula of the complex is

At a certain temperature, the value of the slope of the plot of osmotic pressure (\(\pi\)) against concentration (\(\text{C}\) in mol \(\text{L}^{-1}\)) of a certain polymer solution is 291R.
The temperature at which osmotic pressure is measured is

In the formation of coordination complexes, if the inner \(d\) orbital \((n-1) d\) is used in hybridisation, the complex, is called an inner orbital or low spin or spin paired complex. And if it uses outer \(d\) orbital ( \(n d\) ) in hybridisation (like \(s p^3 d^2\) ), it is called outer orbital or high spin or spin free complex. The degeneracy of the \(d\) orbitals has been removed due to ligand electron-metal electron repulsions in the complex. This splitting of the degenerate levels due to the presence of ligands in a definite geometry is termed as crystal field splitting. For coordination complexes, the magnetic moment is determined by the number of unpaired electrons and is calculated by using the 'spin-only' formula, \(\mu=\sqrt{n(n+2)}\) where \(n\) is the number of unpaired electrons and \(\mu\) is the magnetic moment in units of Bohr magneton (BM). The coordination compounds are of great importance. These compounds are widely present in the mineral, plant and animal worlds and are known to play many important functions in the area of analytical chemistry, metallurgy, biological systems, industry and medicine.
