The first 3 of 20 questions. Unlock the series for the rest, each with a solution.
Q1. Which one of the following statements about the oxides of nitrogen is INCORRECT?
नाइट्रोजन के ऑक्साइडों के विषय में निम्नलिखित में से कौन-सा कथन गलत है?
- A. NO contains an odd number of electrons and is paramagnetic / NO में विषम संख्या में इलेक्ट्रॉन होते हैं तथा यह अनुचुंबकीय है
- B. NO2 dimerises to N2O4 on cooling / NO2 ठंडा करने पर N2O4 में द्विलकीकृत हो जाता है
- C. N2O5 is the anhydride of nitric acid / N2O5 नाइट्रिक अम्ल का एनहाइड्राइड है
- D. N2O is an acidic oxide and the anhydride of nitrous acid / N2O एक अम्लीय ऑक्साइड तथा नाइट्रस अम्ल का एनहाइड्राइड है
Solution
N2O (nitrous oxide) is a neutral oxide, not acidic; NO is also neutral. NO2 is acidic (mixed anhydride), N2O5 is the anhydride of HNO3, and NO is paramagnetic owing to an odd electron. Hence the statement calling N2O acidic is incorrect.
N2O (नाइट्रस ऑक्साइड) एक उदासीन ऑक्साइड है, अम्लीय नहीं; NO भी उदासीन है। NO2 अम्लीय है (मिश्रित एनहाइड्राइड), N2O5, HNO3 का एनहाइड्राइड है, तथा NO एक विषम इलेक्ट्रॉन के कारण अनुचुंबकीय है। अतः N2O को अम्लीय कहने वाला कथन गलत है।
Q2. The first true compound of a noble gas, prepared by Neil Bartlett in 1962 by the reaction of xenon with platinum hexafluoride, was:
किसी अक्रिय गैस का प्रथम वास्तविक यौगिक, जिसे नील बार्टलेट (Neil Bartlett) ने 1962 में ज़ीनॉन की प्लैटिनम हेक्साफ्लुओराइड के साथ अभिक्रिया द्वारा बनाया था, वह था:
- A. XeF4
- B. XeF2
- C. XeO3
- D. Xe[PtF6]
Solution
Bartlett prepared the orange-yellow solid xenon hexafluoroplatinate, formulated as Xe[PtF6], which was the first genuine noble-gas compound; the fluorides XeF2, XeF4 and the oxide XeO3 were characterised later.
बार्टलेट ने नारंगी-पीला ठोस ज़ीनॉन हेक्साफ्लुओरोप्लैटिनेट बनाया, जिसे Xe[PtF6] के रूप में निरूपित किया जाता है, जो प्रथम वास्तविक अक्रिय-गैस यौगिक था; फ्लुओराइड XeF2, XeF4 तथा ऑक्साइड XeO3 बाद में अभिलक्षित किए गए।
Q3. Bleaching powder is manufactured by passing chlorine over dry slaked lime. Its correct chemical formula is best represented as:
विरंजक चूर्ण (bleaching powder) का निर्माण शुष्क बुझे चूने पर क्लोरीन प्रवाहित करके किया जाता है। इसका सही रासायनिक सूत्र सर्वोत्तम रूप में निरूपित किया जाता है:
- A. Ca(OCl)2
- B. CaOCl2
- C. CaCl2
- D. Ca(OH)Cl
Solution
Bleaching powder is the mixed salt CaOCl2 (calcium chloride hypochlorite, Ca(OCl)Cl); Ca(OCl)2 is calcium hypochlorite and CaCl2 is calcium chloride, which are different compounds.
विरंजक चूर्ण मिश्रित लवण CaOCl2 (कैल्शियम क्लोराइड हाइपोक्लोराइट, Ca(OCl)Cl) है; Ca(OCl)2 कैल्शियम हाइपोक्लोराइट है तथा CaCl2 कैल्शियम क्लोराइड है, जो भिन्न यौगिक हैं।
