We extensively study the formation of various molecules in the Interstellar Medium (ISM) via gas-grain interaction. To mimic the dynamic behaviour of the ISM properly, we have modeled for a collapsing Interstellar cloud for the formation of protostar. We consider a two dimensional hydrodynamical flow for this study. We do consider the angular motion in this flow. Total variation diminishing scheme(TVD) is used to study the properties of the Interstellar collapsing cloud. Arm with this sophisticated hydrodynamical model we couple our reasonably large chemical network for gas and grain, to study the chemical evolution during these processes. At the end different observational evidences for the gas phase as well as condensed phase species are summarized with their physical conditions and are compared with our own model.
