I would like to ask if the temperature at which a product is leaving a distillation column(debutanizer) must be equal to the temperature at which it should enter the Reboiler. Is the bottom temperature of the column equals to the temperature at which the product enters the reboiler?

It depends on reboiler configuration. If you have recirculating reboiler without baffle in the tower, then the column bottom product has the same composition and temperature as reboiler feed.
For other types of reboilers (once-through, kettle, recirculating with baffle etc.) this is not the case.

Take a look at this site where you will find schematic diagrams of various types of rebopilers:
I think that will make the answer to your question almost self-evident.
