Organic Chemistry Lab I (Practical) |
CO86 Apply suitable techniques to separate and identify organic compounds from the given mixture. CO87 Perform the experiments for the determination of the functional groups using suitable techniques and check the purity through MP/TLC. CO88 Compile and report the results efficiently and develop communication skills. CO89 Contribute effectively in course-specific interaction. |
Approach in teaching: 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, Quiz |
Separation, purification and identification of components of a mixture of two organic compounds (one liquid and one solid or two solids) using TLC for checking the purity of separated compounds.
Estimation of sulphur by messenger or fusion method.
Estimation of nitrogen by Kjeldahl’s method.
Scheme of Examination
The duration of examination will be 6 hrs.
The following exercise will be set in the examination
Organic Mixture Analysis 30 marks
Quantitative analysis 25 marks
Viva 15 marks
Total 70 marks
This exercise carries 30 marks for the identification of two organic compounds. 6 marks are reserved for the proper selection of separation technique, four marks for proper reporting of result and rest of the 20 marks are kept for the identification of two organic compounds (10 marks each)
Out of two organic compounds, one compound will be so given that its derivative can be obtained under the prevailing conditions of the laboratory.
The exercise carries 20 marks. Distribution is as follows:
Theory and procedure 5 marks
Preparation of solutions 4 marks
Observation 4 marks
Calculation 6 marks
Result 6 marks
Oral questions shall generally be asked over the work assigned to the candidate. The purpose is to find out as to what extent the candidate has understanding the basic principles of chemistry.
