513 K पर \(KMnO_4\) को गर्म करने पर बनने वाली हरी अनुचुम्बकीय प्रजाति (species) है :
Show Hint
\(KMnO_4\) purple होता है जबकि \(K_2MnO_4\) green होता है।
Updated On: Jun 22, 2026
- \(MnO\)
- \(KO_2\)
- \(K_2MnO_4\)
- \(Mn_3O_4\)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
पद 1: प्रश्न को समझना
हमें heating of \(KMnO_4\) पर बनने वाली green paramagnetic species पहचाननी है।
पद 2: मुख्य सूत्र या दृष्टिकोण
Thermal decomposition: \[ 2KMnO_4 \rightarrow K_2MnO_4 + MnO_2 + O_2 \] पद 3: विस्तृत व्याख्या
यहाँ: \[ K_2MnO_4 \] हरा रंग (green) का होता है।
Mn oxidation state: \[ +6 \] Electronic configuration: \[ 3d^1 \] इसलिए यह paramagnetic है।
पद 4: अंतिम उत्तर
अतः सही विकल्प (C) है।
