There is a difference between Evaporation and boiling point.

The molecules present at the surface of a liquid remains in contact with surroundings. If surrounding of liquid is at higher temperature then the molecules present at the surface of liquid start leaving the liquid surface, the phenomenon is known as evaporation. When evaporation and condensation takes place simultaneously then a condition of equilibrium exits at a particular temperature and vapour pressure is developed.

The temperature at which vapour pressure of the substance becomes equal to atmospheric pressure it is called as boiling point.
