Could anybody help me to choose interesting topic to do my presentation in organic chemistry ? :rolleyes:

Esters! The mixture of carboxylic and alcohol group to form compounds with fruity smell... :p That would be my choice!

You can also choose alkenes, how they undergo addition reaction, combustion...

Alkanes, how they undergo substitution reaction, combustion...

I like the subject of the Ester , but when I serch I didn't find anything..

Did you have any link about it ?

Try this:

Let me google that for you (http://www.lmgtfy.com/?q=ester)
