In this study, the von Neumann entropy (entanglement entropy) of $ s-d $ bosons and proton ($ \pi $) - neutron ($ \nu $) bosons in the even-even Molybdenum (${^{94-102}{\rm{Mo}}} $) isotopes, within the framework of the Interacting Boson Model-2 (IBM-2), has been calculated and analyzed. In order to compare the results, the energy spectra, quadrupole moment, and the expectation value of the s-boson number operator of Mo isotopes have been obtained. The results showed that ${^{94}{\rm{Mo}}} $ has the minimum entanglement of $ s $ and $ d $ bosons and ${^{102}{\rm{Mo}}} $ nucleus has the maximum entanglement of $ s $ and $ d $ bosons. Therefore, these nuclei are spherical ($U(5)$) and $\gamma$-unstable ($SO(6)$) nuclei, respectively, and other observables confirm this result. Also, the value of the entanglement entropy of the $ \pi $ and $ \nu $ bosons is constant by changing the control parameter. So, it does not show any transition.
