During the change of O2 to O2-the electron adds on π* orbital. Molecular orbital configuration of O2 (total e- =16)
Which of the two ions from the list given below have the geometry that is explained by the same hybridization of orbitals
D.
Hybridization of the given molecule is
Therefore, both have the same hybridization.
Four diatomic species are listed below. Identify the correct order in which the bond order is increasing in them.
NO< O2-<C22- < He2+
O2- <NO< C22- < He2+
C22- < He2+ <O2- <NO
C22- < He2+ <O2- <NO
D.
C22- < He2+ <O2- <NO
Which one of the following pairs is isostructural (i.e., having the same shape and hybridization)?
[BCl3 and BrCl3]
[NH3 and NO3-]
[NF3 and BF3]
[NF3 and BF3]
D.
[NF3 and BF3]
If a number of bond pairs and lone pairs are same for the given pairs, they are isostructural.
The Correct order of increasing bond length of C - H, C-O, C - C and C = C is
C - C < C=C < C - O < C - H
C - O < C - H < C - C < C = C
C - H < C - O < C - C < C= C
C - H < C = C < C - O < C - C
D.
C - H < C = C < C - O < C - C
C - H: 0.109 nm
C = C : 0.134 nm
C - O: 0.143 nm
C - C : 0.154 nm
Therefore, Bond length order is
C - H < C = C < C- O < C - C
