ON TIPS NOTES

Note taking is a skill that we use in many walks of life : at school, university and in the world of work. However, accurate note making requires a thorough understanding of concepts. We, at Oswaal, have tried to encapsulate all the chapters from the given syllabus into the following On TIPS NOTES. These notes will not only facilitate better understanding of concepts, but will also ensure that each and every concept is taken up and every chapter is covered in totality. So go ahead and use these to your advantage... go get the OSWAAL ADVANTAGE !!

CHAPTER 1 : Carbon And its Compounds

Key Points and Concepts :

S. No.

1. They are readily soluble in organic solvent. They are not soluble in organic solvent.

2. They do not ionise. They ionise in organic medium.

3. They are bad conductors of heat and electricity.

They are good conductors of heat and electricity.

4. They have weak force of attraction between the molecules.

They have strong force of attraction between the molecules.
