Answer the following questions : Explain the term saturated hydrocarbons with examples.

Answer the following questions : Classify into alkanes, alkenes and alkynes: Ethane Ethene Methane Propene Ethyne Propyne Butane Pentane.

Answer the following questions : Classify into straight chain carbon compounds, branched chain carbon compounds, and ring carbon compounds: Propene Butane Iso-butane Cyclopentane Benzene Isobutylene.

Answer the following questions : Observe the straight chain hydrocarbons given below and answer the following questions. Which of the straight chain compounds from A and B is saturated and unsaturated straight chains ?

Answer the following questions: By how many -CH_2- (methylene) units do the formulae and the fist two members of homologous series ofalkane, methane (CH_4) and ethane (C_2H_6) differ? Similarly, by how many -CH_2- Units do the neighboring members ethane (C_2H_6) and propane (C_3H_8) differ from each other?

Carbon forms a large number of compounds because of its two unique properties formed many have long straight chains of carbon, branched chains of carbon or rings of carbon. In these compounds, carbon atoms may form single, double or triple covalent bonds. Compounds in which the carbon atoms are linked to each other by single bonds are called saturated carbon compounds whereas compounds having at least one carbon-carbon double or triple bond are called unsaturated carbon compounds. Compounds containing only carbon and hydrogen are known as hydrocarbons. Based on the above information, answer the following questions. iii. What are saturated hydrocarbons? Give one example.
