The paramagnetic behaviour depends on the number of unpaired electrons. Using the electronic configurations:
\(Complex\) | \(\text{Number of unpaired electrons}\) | \(\mu = \sqrt{n(n+2)}\) B.M. |
---|---|---|
\([\text{Co(H}_2\text{O)}_6]^{2+}\) | 3 | 3.87 |
\([\text{Fe(H}_2\text{O)}_6]^{2+}\) | 4 | 4.89 |
\([\text{Mn(H}_2\text{O)}_6]^{2+}\) | 5 | 5.92 |
\([\text{Cr(H}_2\text{O)}_6]^{2+}\) | 4 | 4.89 |
The least paramagnetic complex is \([\text{Co(H}_2\text{O)}_6]^{2+}\), as it has the fewest unpaired electrons (3).
The structure of the major product formed in the following reaction is:
The steam volatile compounds among the following are:
The structure of the major product formed in the following reaction is:
If \[ \frac{dy}{dx} + 2y \sec^2 x = 2 \sec^2 x + 3 \tan x \cdot \sec^2 x \] and
and \( f(0) = \frac{5}{4} \), then the value of \[ 12 \left( y \left( \frac{\pi}{4} \right) - \frac{1}{e^2} \right) \] equals to:
