Abstract

Molecular clouds when collapsed due to their self-gravity leads to the formation of the protostellar envelope and then leads to the formation of protoplanetary disc and planets. Thus it is evident that this molecular cloud provides chemical materials for further evolution which lead to varied Complex chemistry. Nearly 100s of complex molecules have been observed in these molecular clouds and some of them are precursors of prebiotic chemistry. Dust grains play an important role in the formation of these complex specifies through surface chemistry. Understanding cloud chemistry through the gas-grain surface chemistry is of vital importance and therefore modeling these molecular clouds will help us to see the revolutions for various physical parameters. At the beginning, I showed the observation which I tried doing through Casa and then I showed Nautilus 3-phase model.
