Rationale and Objective


Keeping in view the recent developments in Science and the present needs in Industries, the curriculum of Engineering Chemistry has been revised so that the Engineers or Technicians may have a better knowledge of Chemistry, especially regarding the application of the subject in various fields of Industries. An emphasis, in this direction, has been made in the curriculum.

A new chapter on Environmental Chemistry has been introduced to make the students acquainted with the various pollution hazards which is becoming more critical everyday.

The following topics are so chosen that through their contents the students are able to develop knowledge, skill and scientific attitude. It will enable them to distinguish, differentiate, analyze and solve engineering problems.
