1. Why is the carbon- carbon bond strong and stable?
2. Write the structural formula and all the possible isomers of heptane.
3. Define a micelle. Will a micelle be formed in an organic solution? Why or why not?
4. What are the two possible carbon compounds with the molecular formula C₃H₆O?
5. Mention the oxidising agent in the oxidation reaction involving ethanol.
6. Write the names and draw the structure of the first two members of the
--CO-- homologous series.
7. Why do substances burn with or without flames? Why are saturated organic compounds usually preferred as fuels?
8. Write the number of bonds present in the molecule of the fifth member of the homologous series of alkynes.
9. Draw the structures of : Pentanal, propanone, methanoic acid, hexanone and benzene.
10. Why is pure acetic acid called 'glacial acetic acid'? What percentage of acetic acid in water yields vinegar?
11. Why are organic acids weak? Draw the structure of any two carboxylic acids.
12. What are detergents? Mention in context of their constituents.
13. Draw the electron dot structure of : pentanol, flourine and water.
14. What type of mixture (colloid, solution, suspension) is a mixture of water and soap?
15. In the formation of soap, common salt is added. Why? Also, mention what is the saponification reaction.
16. How does ethanoic acid react with carbonates and hydrogen carbonates? Is CH₃COOC₂H₅ an ester? If yes, mention how it reacts with NaOH.
There you go, mate.

Zetroblaze:
Thanks again! :)
By the way 2nd one is heptane or hex?
Oo..sorry I got it..it's the 7 carbon atom
My pleasure. Its heptane. (Having 7 carbon atoms) Btw, best of luck!
