• INTRODUCTION: Hydrocarbons are organic compounds which contain carbon and hydrogen only. The number of such compounds is very large because of the property of catenation. Hydrocarbons have been divided into various classes on the basis of structure of the chain or size and nature of the ring.
• Important 2nd year chemistry chapter 8 exercise short questions for Intermediate part-II students.
• If all the valencies of the carbon atoms in a molecule are fully satisfied and these cannot further take up any more hydrogen atoms, then the hydrocarbons are named as saturated hydrocarbons or alkanes. The compounds of carbon and hydrogen in which all the four valencies of carbon are not fully utilized and they contain either a double or a triple bond, such compounds are called unsaturated hydrocarbons. Those unsaturated hydrocarbons which contain a double bond are called alkenes while those containing a triple bond are called alkynes. Classification of hydrocarbons has been.
