JEE Mains · Chemistry · STD 12 - 5. Co-ordination chemistry
The Spin only magnetic moment value of square planar complex \(\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}\left(\mathrm{NH}_2 \mathrm{CH}_3\right)\right] \mathrm{Cl}\) is \(B.M.\) (Nearest integer) (Given atomic number for \(\mathrm{Pt}=78\)
- A \(1\)
- B \(2\)
- C \(3\)
- D \(0\)
Answer & Solution
Correct Answer
(D) \(0\)
Step-by-step Solution
Detailed explanation
\(\mathrm{Pt}^{2+}\left(\mathrm{d}^8\right)\) \(\mathrm{Pt}^{2+} \rightarrow \mathrm{dsp}^2\) hybridization and have no unpaired e-s. \(\therefore\) Magnetic moment \(\mathrm{o} 0\)
