- This work discuses the effect of the QCD coupling constant ($α_c$) on various physical properties of compact stars in the framework of the Tolman IV potential admitting the equation of state of MIT bag model with nonzero value of mass of strange quark mass ($m_s$). The internal matter, consisting of the deconfined phase of the $3$-flavour quark, is overall charge neutral due to the presence of electrons and is assumed to be strongly interacting. Interestingly, it is noted that the coupling constant $α_c$ has an upper limit due to thermodynamic consistency and affects the stability of the stellar structure in terms of energy per baryon ($E_B$). Present model is suitable to study the properties of stars with mass of approximately $\leq 2.00~M_{\odot}$. The predicted radii of a few known stars from our model are in good agreement with the estimated values of radius obtained from the observations. Necessary energy conditions are obeyed inside the stellar configuration. Various stability conditions are carried out and it is found that within the range of parameter space used here the model is stable.
