Is it true that dispersion of light also takes place in parallel sided glass slab but not to that extent as in prism .
I read in book that :
Dispersion takes place inside the slab, but, since the rays which emerge from the slab all run parallel to one another, the dispersed colours recombine to form white light again, and no dispersion is observed except at the very edges of the beam.
It follows that the dispersion of white light through a parallel-sided glass slab is not generally a noticeable effect.

No. In case of a glass slab the angle of deviation is zero. So the dispersion of light to any extent is impossible.
In case of a glass slab the incident and the emergent rays are parallel. So, there is no chance of recombination of colors of light if in case there is any dispersion.
