Preamble The Board of Studies in Chemistry (PG) at its meeting held on 21.06.2010 considered the introduction of Credit Semester System (CSS) in affiliated colleges for the PG programmes in Chemistry and resolved to implement the CSS pattern from 2010 admission onwards. The revised programme pattern; syllabus, distribution of credits and scheme of evaluation, etc. approved by the Board are given below: Pattern of the Programme (a)

The name of the programme shall be M.Sc. Chemistry under CSS pattern.

(b)

The programme shall be offered in four semesters within a period of two academic years.

(c)

Eligibility for admission wi ll be as per the rules laid down by the University from time to time.

(d)

Details of the programme offered for the programme are given in Table I. The programme shall be conducted in accordance with the programme pattern, scheme of examination a nd syllabus prescribed. Of the 25 hours per week, 12 hours shall be allotted for theory, 12 hours for practicals and 1 hour for seminar.

Theory Courses In each semester there will be three theory courses. All the theory courses in the first and second semesters are core papers. In the third semester there will be two core theory courses and one elective course. Colleges can choose any one of the elective courses given in table 1. In the fourth semester there will be one core courses and two elective courses. College can choose any two elective courses from those given in table 1. However a candidate may be permitted to choose any other elective courses without giving any lecture classes. Practicals: In each semester there will be three core practic al courses (2 credits each). However practical examination will be conducted only at the end of the second semester for CHPO1, CHPO2, CHPO3 and at the end of fourth semester for CHPO4, CHPO5, CHPO6. Project and Viva Voce : Each student will have to do an independent research project work during the programme under the guidance of a faculty member of the college/ scientists of recog nized research institutions and to submit the dissertation at the end of the fourth semester for evaluation (5 credits). There will be a comprehensive viva voce (3 credits) at the end of 2

the fourth semester. The viva voce will be based on the theory and practical courses and the project work.
