Combustion of Hydrocarbons Alkanes
Electrophilic Addition Alkenes
Why certain compounds are called hydrocarbons? Write the general formula for homologous series of alkanes, alkenes and alkynes and also draw the structure of the first member of each series. Write the name of the reaction that converts alkenes into alkanes and also write a chemical equation to show the necessary conditions for the reaction to occur.
Which of the following hydrocarbons undergo addition reactions :C2H6, C3H8, C3H6, C2H2, and CH4
Mention two differences between saturated and unsaturated hydrocarbons.
(a) Give the general formula of an: (i) alkane, (ii) alkene, and (iii) alkyne.(b) Classify the following compounds as alkanes, alkenes, and alkynes: C2H4 , C3H4 , C4H8 , C5H12 , C5H8 , C3H8 , C6H6.
(a) Differentiate between alkanes and alkenes. Name and draw the structure of one member of each.(b) Alkanes generally burn with clean flame. Why?
Unsaturated hydrocarbons contain multiple bonds between the two C-atoms and show addition reactions. Give the test to distinguish ethane from ethene.
Which of the following will undergo addition reactions?
Explain why, alkanes are excellent fuels.
(a) What are hydrocarbons? Give examples.(b) Give the structural differences between saturated and unsaturated hydrocarbons with two examples each.(c) What is a functional group? Give examples of four different functional groups.

Which of the following hydrocarbons will give substitution reactions and why?CH4, C3H6, C3H8, C4H6, C5H12, C5H10
(a) What are hydrocarbons? Explain with examples.(b) Explain the meaning of saturated and unsaturated hydrocarbons with two examples each. (c) Give the names and structural formulae of one saturated cyclic hydrocarbon and one unsaturated cyclic hydrocarbon. (d) Give one example of a hydrocarbon, other than pentane, having more than three isomers. (e) How many isomers of the following hydrocarbons are possible? (i) C3H8 (ii) C4H10 (iii) C5H12 (iv) C6H14
(a) What is the general formula of alkenes? Identify the alkenes from the following: Ð¡2ÐÂ6, Ð¡2ÐÂ4, C3H4, C2H2, C3H6 (b) Which of the following can give addition reactions? Ð¡2ÐÂ6, C3H4, C3H6, C2H2, CH4 Give reason for your choice.
