CO150: Separate and identify the given organic binary mixtures using water, saturated solution of sodium bicarbonate and dilute sodium hydroxide. CO151: Prepare Laissagne’s solution and detect the presence of extra element in organic compound CO152: Identify the functional groups in simple organic compounds by performing step-wise qualitative tests and prepare suitable derivatives accordingly. CO153: Compile and report the results efficiently, and develop communications skills. CO154: Contribute effectively in course-specific interaction. |
Approach in teaching: Power point presentation, laboratory instructions and demonstrations.
Learning activities for the students: Peer learning, hands-on-learning, interpretation of data, record writing and learning through virtual labs.
|
Conduction of experiments, lab records, viva voce.
