HF has highest boiling point among hydrogen halides, because it has:
Strongest van der Waal’s interactions
Lowest ionic character
Strongest hydrogen bonding
Lowest dissociation enthalpy
Among the following molecules/ ions,
Which one is diamagnetic and has the shortest bond length?
C
N
O2
The correct statement among I to III are:
(I) Valence bond theory cannot explain the color exhibited by transition metal complexes.
(II) Valence bond theory can predict quantitatively the magnetic properties of transition metal complexes.
(III) Valence bond theory cannot distinguish ligands as weak and strong field ones.
(I) and (III) only
(II) and (III) only
(I), (II) and (III)
(I) and (II) only
The ion that has sp3d2 hybridization for the central atom, is:
[ICl4]-
[ICl2]-
[IF6]-
[BrF2]-
A.
[ICl4]-
[ICl4]- have 4 B.P. and 2 L.P (steric number 6). So central atom is involved in sp3d2 hybridization.
During the change of O2 to O, the incoming electrons goes to the orbital;
π*2Px
π2Px
σ*2Px
π2Py
