The d- and f-Block Elements MCQ questions with answers
The first 3 of 20 questions. Unlock the series for the rest, each with a solution.
Q1. The reaction between iodide ions and persulphate (peroxodisulphate) ions in solution is catalysed by which of the following ions?
विलयन में आयोडाइड आयनों तथा परसल्फेट (परऑक्सोडाइसल्फेट) आयनों के बीच अभिक्रिया निम्नलिखित में से किस आयन द्वारा उत्प्रेरित होती है?
- A. Zn2+
- B. Fe3+
- C. Sc3+
- D. Ca2+
Solution
Fe3+ catalyses this reaction by shuttling between the +3 and +2 states, a classic example of homogeneous catalysis by a transition-metal ion exhibiting variable oxidation states.
Fe3+ इस अभिक्रिया को +3 तथा +2 अवस्थाओं के बीच परिवर्तित होकर उत्प्रेरित करता है, जो परिवर्तनशील ऑक्सीकरण अवस्थाएँ प्रदर्शित करने वाले संक्रमण-धातु आयन द्वारा समांगी उत्प्रेरण का एक प्रतिष्ठित उदाहरण है।
Q2. In which one of the following compounds does manganese exhibit the +6 oxidation state?
निम्नलिखित में से किस एक यौगिक में मैंगनीज +6 ऑक्सीकरण अवस्था प्रदर्शित करता है?
- A. KMnO4
- B. MnO2
- C. Mn2O7
- D. K2MnO4
Solution
In K2MnO4 (potassium manganate) manganese is +6. In KMnO4 and Mn2O7 it is +7, while in MnO2 it is +4.
K2MnO4 (पोटैशियम मैंगनेट) में मैंगनीज +6 होता है। KMnO4 और Mn2O7 में यह +7 होता है, जबकि MnO2 में यह +4 होता है।
Q3. Which of the following is NOT regarded as a transition element?
निम्नलिखित में से किसे संक्रमण तत्व नहीं माना जाता है?
- A. Cr
- B. Zn
- C. Cu
- D. Fe
Solution
Zinc has a completely filled 3d orbital (3d10) in its atom and its common +2 ion, so it is not classed as a transition element; Cu, Fe and Cr have incompletely filled d orbitals.
जिंक के परमाणु तथा इसके सामान्य +2 आयन में पूर्णतः भरा हुआ 3d ऑर्बिटल (3d10) होता है, अतः इसे संक्रमण तत्व के रूप में वर्गीकृत नहीं किया जाता; Cu, Fe तथा Cr में अपूर्ण रूप से भरे हुए d ऑर्बिटल होते हैं।
