The interaction energy between two temporary dipoles is proportional to (where r is the distance between the two particles)

In $$Fe{(CO)}_{5}$$, the $$Fe-C$$ bond possess:

Carbon - halogen bond is most susceptible to cleave in

Coordinate bond is not present in

Which of the following has non-zero dipole moment?

Which of the following combinations is not allowed (assumed z-axis is internuclear axis).

The compound with lowest dipole moment is.

Which of the following compounds has the largest
dipole moment? 

$$\rm{O-H}$$  bond length is  $$1 \mathop {\text{A}}\limits^ \circ $$  and it's dipole moment is  $$1.5D$$.  So the fraction of the charge on oxygen is
