The first 3 of 20 questions. Unlock the series for the rest, each with a solution.
Q1. The number of geometrical isomers possible for the square planar complex [Pt(NH3)2Cl2] is:
वर्ग समतलीय संकुल [Pt(NH3)2Cl2] के लिए संभव ज्यामितीय समावयवियों की संख्या है:
- A. 2
- B. 1
- C. 4
- D. 3
Solution
A square planar MA2B2 complex exists as cis and trans forms only, so there are two geometrical isomers.
एक वर्ग समतलीय MA2B2 संकुल केवल सिस और ट्रांस रूपों में विद्यमान होता है, अतः दो ज्यामितीय समावयवी होते हैं।
Q2. The violet colour of the hexaaquatitanium(III) ion, [Ti(H2O)6]³⁺, is best explained by which of the following?
हेक्साऐक्वाटाइटेनियम(III) आयन, [Ti(H2O)6]³⁺, के बैंगनी रंग की सबसे अच्छी व्याख्या निम्नलिखित में से किससे होती है?
- A. An s→p electronic transition within the titanium ion / टाइटेनियम आयन के भीतर एक s→p इलेक्ट्रॉनिक संक्रमण
- B. A d–d transition of its single d-electron from the t2g to the eg set / इसके एकमात्र d-इलेक्ट्रॉन का t2g से eg समुच्चय में एक d–d संक्रमण
- C. A charge-transfer transition from ligand to metal / लिगैंड से धातु की ओर एक आवेश-अंतरण संक्रमण
- D. The presence of three unpaired d-electrons on titanium / टाइटेनियम पर तीन अयुग्मित d-इलेक्ट्रॉनों की उपस्थिति
Solution
Ti³⁺ is a d¹ ion; absorption of visible light promotes the single electron from the t2g to the eg level (a d–d transition), and the colour seen is complementary to the light absorbed.
Ti³⁺ एक d¹ आयन है; दृश्य प्रकाश के अवशोषण से एकमात्र इलेक्ट्रॉन t2g से eg स्तर में उन्नत हो जाता है (एक d–d संक्रमण), और जो रंग दिखाई देता है वह अवशोषित प्रकाश का पूरक होता है।
Q3. The correct IUPAC name of the coordination compound [Co(NH3)4Cl2]Cl is:
उपसहसंयोजन यौगिक [Co(NH3)4Cl2]Cl का सही IUPAC नाम है:
- A. tetraamminedichloridocobalt(III) chloride / टेट्राऐम्मीनडाइक्लोरिडोकोबाल्ट(III) क्लोराइड
- B. tetraamminedichloridocobaltate(III) chloride / टेट्राऐम्मीनडाइक्लोरिडोकोबाल्टेट(III) क्लोराइड
- C. dichloridotetraamminecobalt(III) chloride / डाइक्लोरिडोटेट्राऐम्मीनकोबाल्ट(III) क्लोराइड
- D. tetraamminedichloridocobalt(II) chloride / टेट्राऐम्मीनडाइक्लोरिडोकोबाल्ट(II) क्लोराइड
Solution
Ligands are named alphabetically (ammine before chlorido) with di/tetra multiplying prefixes, the metal of a cationic complex keeps its element name with oxidation state (III) in brackets, followed by the counter ion.
लिगैंडों को वर्णानुक्रम में नामित किया जाता है (chlorido से पहले ammine) जिनके साथ di/tetra गुणक उपसर्ग लगते हैं, धनायनी संकुल की धातु अपना तत्व नाम बनाए रखती है और उसकी ऑक्सीकरण अवस्था (III) कोष्ठक में दी जाती है, तत्पश्चात प्रतिआयन।
