CY101 : Chemistry Theory (3-1-0) 4

credits

Overall Learning Objectives of the Course:

Present day fast evolving technologies are based on scientific principles. Hence a clear and

sufficient comprehension of basic sciences is imperative for engineering students.

The chemistry course is intended to provide chemical concepts most relevant to engineering

students and demonstrates them in an applied context. Problems solving & conceptually

driven approach is used which help engineering students to develop the quantitative &

qualitative skills necessary to succeed in the course.
