The students will be able to – CO111: learn the use of green chemistry principles and processes in laboratory reactions as a benign approach. CO112: compare the advantages of green procedures over conventional synthesis. CO113: assign structures to simple molecules on the basis of infra-red and nuclear magnetic resonance spectroscopy. CO114: estimate the different functional groups i.e. hydroxyl (monohydric, dihydric, trihydric and phenols) and amino by different methods. CO115: estimate the saponification value of different saturated and unsaturated oil. |
