Chemie kann mir bitte jemand helfen?

Hallo, kann mir einer helfen muss morgen ein Referat über Carbonssäureester halten und brauch diese ester in der Strukturformel gezeichnet .also ich muss sie in die Valenzstrichformel zeichnen. Im Internet kommen komische Abbildungen die ich nicht in der valenzstrichformel zeichnen kann.

The rest you have to draw yourself. You just have to adjust the chain lengths…

The ester bond is always the same, only the numbers of carbon atoms differ.

Take the first: there is formic acid, which has a carbon atom. There is also -ethyl ester, i.e. 2 carbon atoms on the right.

Formic acid is the trivial name for methaneic acid (1 C atom), acetic acid of ethanic acid (2 C atoms), propionic acid of propanoic acid (3 C atoms), butyric acid of 4 C atoms. Then I still know Valerian acid, which is the trivial name of pentanoic acid (5 C atoms).

You need to count the acid and the alkyl residue individually…and it’s not 6!

Count the carbon atoms and draw it as above in the AnanasAroma

They should also be in your ChemistryBook…

Depending on this, both chains may have to be adjusted.

You should know the names of the residues and acids if you are already with the esters.
