Where do I get a PDF of the engineering chemistry book for the Anna University exams?

Being a student of Anna University, you should first consult your Chemistry teacher for the study materials. You can also ask your seniors to recommend some books for the same. There is a chance that they might inform you of a PDF that will help you get good marks.

Apart from this, some websites that provide PDFs are

1. Library Genesis

2. PDF Drive - Search and download PDF files for free.

Both these websites will help you gain access to the required PDFs. Another simple option is to simply browse google and look for the pdf of the book.
