Q1. According to VSEPR theory, what is the shape of the sulphur dioxide (SO2) molecule?
VSEPR सिद्धांत के अनुसार, सल्फर डाइऑक्साइड (SO2) अणु की आकृति क्या है?
- A. Trigonal planar / त्रिकोणीय समतलीय
- B. Trigonal pyramidal / त्रिकोणीय पिरामिडीय
- C. Linear / रैखिक
- D. Bent (angular) / मुड़ी हुई (कोणीय)
Solution
Sulphur in SO2 is sp2 hybridised with two bonding regions and one lone pair, giving a bent (angular) shape.
SO2 में सल्फर sp2 संकरित है जिसमें दो बंधी क्षेत्र तथा एक एकाकी युग्म है, जिससे मुड़ी हुई (कोणीय) आकृति बनती है।
Q2. The hybridisation of the central xenon atom in XeF4 is:
XeF4 में केंद्रीय ज़ीनॉन परमाणु का संकरण है:
- A. sp3d2
- B. sp3d3
- C. sp3
- D. sp3d
Solution
XeF4 has 6 electron pairs around Xe (4 bond pairs + 2 lone pairs), requiring sp3d2 hybridisation, which gives it a square planar shape.
XeF4 में Xe के चारों ओर 6 इलेक्ट्रॉन युग्म (4 बंध युग्म + 2 एकाकी युग्म) होते हैं, जिसके लिए sp3d2 संकरण आवश्यक है, जो इसे वर्गाकार समतलीय आकृति प्रदान करता है।
Q3. Which one of the following molecules does NOT form hydrogen bonds?
निम्नलिखित में से कौन-सा अणु हाइड्रोजन आबंध नहीं बनाता है?
- A. HCl
- B. H2O
- C. NH3
- D. HF
Solution
Hydrogen bonding requires H attached to the highly electronegative F, O or N; HCl lacks such an atom, while HF, H2O and NH3 all form hydrogen bonds.
हाइड्रोजन आबंधन के लिए H का अत्यधिक विद्युतऋणात्मक F, O या N से जुड़ा होना आवश्यक है; HCl में ऐसा कोई परमाणु नहीं है, जबकि HF, H2O तथा NH3 सभी हाइड्रोजन आबंध बनाते हैं।
