How many geometrical isomers are possible for [Cr(NH₃)2Cl₄]^{- ?

For octahedral [Ma₂b4], 2 geometrical isomers exist: cis (two NH₃ adjacent) and trans (opposite). This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

What is the hybridization of [FeF₆]^{3- ?

Given: What is the hybridization of [FeF₆]^{3- ? Formula: Fe³⁺ ( d⁵ ) with weak field F^- in an octahedral field is high spin, using outer orbitals ( sp³d² ).. Substitution: Substituting given values into formula as per NCERT 2026-27 method. Calculation: Simplifying step by step with proper SI units like m/s², J kg⁻¹ K⁻¹, 10⁻⁵, A m⁻¹ etc. Final Result: The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
