JEE Mains · Chemistry · STD 12 - 5. Co-ordination chemistry
A metal complex with a formula \(\mathrm{MC} \ell_4 \cdot 3 \mathrm{NH}_3\) is involved in \(\mathrm{sp}^3 \mathrm{~d}^2\) hybridisation. It upon reaction with excess of \(\mathrm{AgNO}_3\) solution gives ' x ' moles of AgCl. Consider ' x ' is equal to the number of lone pairs of electron present in central atom of \(\mathrm{BrF}_5\). Then the number of geometrical isomers exhibited by the complex is ______.
- A 4
- B 6
- C 8
- D 2
Answer & Solution
Correct Answer
(D) 2
Step-by-step Solution
Detailed explanation
1 lone pair hence 1 mole AgCl. Complex is \(\left[\mathrm{M}\left(\mathrm{NH}_3\right)_3 \mathrm{Cl}_3\right] \mathrm{Cl}\). It shows 2 geometrical isomers \(\left(\mathrm{Ma}_3 \mathrm{~b}_3\right.\) type) facial (fac) & meridional (Mer)
