Scheme of Examination

 

The duration of examination will be 5 hrs.

The following exercise will be set in the examination

 

Synthesis (any two)                                                                     58 marks

Viva                                                                                           12 marks

Total                                                                                              70 marks

 

Synthesis: 

Students will be allotted two synthesis of 29 marks each. The yield, crystallization and recording of melting point will be given due consideration while awarding marks.

Viva

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 understood the basic principles.
