Practice question

Given: What is the hybridization of [PtCl₄]^{2- ? These values define the system as per NCERT data. Formula: Pt²⁺ ( d⁸ ) with 4 Cl^- ligands in a square planar geometry uses dsp² hybridization.. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: Substituting values like 1.2 × 10⁻⁵, 236 J kg⁻¹ K⁻¹, CH₃CH₂NH₂ etc. into the formula and simplifying step by step. Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kg⁻¹ K⁻¹, m/s², 10⁻⁵ are properly used as per NCERT.
