Molecular Orbital Theory | MCQs
-
A. None of these
-
B. CN⁻
-
C. NO
-
D. O2
Explanation
Two species are isoelectronic if they have the same number of electrons.
N₂ has 14 electrons (7 from each nitrogen atom).
CN⁻ also has 14 electrons (6 from carbon, 7 from nitrogen, and 1 extra due to the negative charge).
-
A. 10Dq
-
B. 20Dq thermic
-
C. 8Dq
-
D. 0Dq
Explanation
In crystal field theory (CFT), the energy gap between the t2g and eg sets is denoted by 10Dq.
ایتھیلین میں، کتنے غیر ہائبرڈائزڈ پی - مدار موجود ہیں؟
-
A. 4
-
B. None of these
-
C. 2
-
D. 1
Explanation
- In ethylene (C2H4), each carbon atom undergoes hybridization, leaving one unhybridized p-orbital per carbon atom.
- These two unhybridized p-orbitals overlap to form the π-bond in the double bond.
