The main aim of this paper is to study the fomation of various complex molecules in the Interstellar Medium (ISM) via gas-grain interaction by taking into account more realistic physical conditions in or around the molecular cloud. Due to this reason, we carry out a two dimensional hydrodynamical simulation of the collapsing phase of a proto-star. Total variation diminishing scheme (TVD) is used to study the properties of the Interstellar collapsing cloud. Our hydrodynamic model is capable of mimicing evolution of the physical properties during the formation of a proto-star. 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. Our model confirms that the chemical composition are highly sensitive to the dynamic behavior of the collapsing cloud, specifically on the density and temperature distribution.
