*The general $U(1)$ extension of the Standard Model is an interesting scenario where the three generations of the right handed neutrinos are introduced. *

In this scenario an additional scalar is also added in the model which induces the Majorana mass term after the symmetry breaking.

Such a model is specially interesting due to the presence of a neutral gauge boson, $Z^\prime$, which has a very rich phenomenology.

The interaction between the $Z^\prime$ and the other particles are governed by the existence of the general $U(1)$ charges after the

anomaly cancellation. In this talk we will discuss a variety of such phenomenologies, for example neutrino mass, Higgs production from the $Z^\prime$.

It is interesting to mention that such models can also contain a dark matter candidate. The constraints on the relevant model parameters have been calculated using the results obtained from the Run 2 of the Large Hadron Collider.
