During conversion of R-OH to R-Cl conversion, SOCl_(2) is a more suitable reagent as compared to HCl, PCl_(5) or PCl_(3) -why?

2 mol of PCl_5(g) is heated at a given temperature in a closed vessel of volume 2L. As a result, PCl_5(g) dissociates and forms PCl_3(g) and Cl_2(g) . When the dissociation reaction reaches equilibrium, it is found that 50% of PCl_5(g) has dissociated. K_c for the reaction is
