Practice question

Given: What is the product when (CH₃)2NH reacts with HNO₂ ? These values define the system as per NCERT data. Formula: Secondary amines like (CH₃)2NH react with HNO₂ to form yellow oily N-nitrosoamines, (CH₃)2N-N=O, without gas evolution.. 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.
