JEE Main 2025 — Coordination Compounds Question with Solution

A metal complex with a formula ${\mathrm{MCl}}_4\cdot 3{\mathrm{NH}}_3$ 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 _________.
