Q1. On which electronegativity scale is the value of fluorine assigned as approximately 4.0, the highest of all elements?
किस विद्युत्ऋणात्मकता मापक्रम पर फ्लुओरीन का मान लगभग 4.0 निर्धारित किया गया है, जो सभी तत्वों में सर्वाधिक है?
- A. Sanderson scale / सैंडरसन मापक्रम
- B. Allred–Rochow scale / ऑलरेड–रोको मापक्रम
- C. Pauling scale / पॉलिंग मापक्रम
- D. Mulliken scale / मुलीकन मापक्रम
Solution
On the Pauling scale, fluorine is assigned the highest electronegativity of about 4.0, against which other elements are compared.
पॉलिंग मापक्रम पर, फ्लुओरीन को लगभग 4.0 की सर्वाधिक विद्युत्ऋणात्मकता दी गई है, जिसकी तुलना में अन्य तत्वों की तुलना की जाती है।
Q2. In a nitrogen molecule (N2) the triple bond consists of how many sigma (σ) and pi (π) bonds respectively?
नाइट्रोजन अणु (N2) में त्रिबंध क्रमशः कितने सिग्मा (σ) और पाई (π) बंधों से मिलकर बना होता है?
- A. 3 σ and 0 π / 3 σ और 0 π
- B. 1 σ and 2 π / 1 σ और 2 π
- C. 0 σ and 3 π / 0 σ और 3 π
- D. 2 σ and 1 π / 2 σ और 1 π
Solution
A triple bond is made up of one σ bond and two π bonds, so N2 has 1 σ and 2 π bonds.
एक त्रिबंध एक σ बंध और दो π बंधों से मिलकर बना होता है, अतः N2 में 1 σ और 2 π बंध होते हैं।
Q3. According to Molecular Orbital Theory, what is the bond order of the nitric oxide (NO) molecule?
आण्विक कक्षक सिद्धांत (Molecular Orbital Theory) के अनुसार, नाइट्रिक ऑक्साइड (NO) अणु की बंध कोटि (bond order) कितनी है?
- A. 2.0
- B. 2.5
- C. 1.5
- D. 3.0
Solution
NO has 15 electrons, giving 10 bonding and 5 antibonding electrons, so bond order = (10 − 5)/2 = 2.5.
NO में 15 इलेक्ट्रॉन होते हैं, जिससे 10 बंधक तथा 5 प्रतिबंधक इलेक्ट्रॉन मिलते हैं, अतः बंध कोटि = (10 − 5)/2 = 2.5।
