Reflection is when a ray of light when incident on a particular surface at some angle $\theta$, bounces off from the surface making an angle $2 \theta$ with the incident ray.

In some cases however, only a fraction of the incident ray is reflected and the rest is transmitted through the medium.

The reflected ray, incident ray and the normal at the point of incidence lie on the same plane.

Diffraction on the other hand is a completely different stuff. It is associated with the bending of light around an obstacle.
The diffraction effects are significant only when the Diffraction objects are nearly of the same order of size as the wavelength of light.
