Hello,

These are chapters of CBSE Class 12 Chemistry.

All these fall under the category Physical and Inorganic Chemistry.

For these chapters, NCERT text book plays a key role. You have to thoroughly go through the text and make short notes. In board exam, you will find theory questions from these chapters. Make note of any formula that you come across.

By solving textual exercises, you can gain better grip.

Hope this helps.

Thanks.
