1. Naming esters

2. carboxylic acid + alcohol ester +water

3. The name of the ester Begins with the prefix from the alcohol (meth-, eth-, pro- etc.) Ends with the prefix from the acid (meth-, eth-, pro- etc.) and then -ate

4. Methanol + butanoic acid -> methyl butanoate + water

5. Begins with the prefix from the alcohol (meth-, eth-, pro- etc.) Ends with the prefix from the acid (meth-, eth-, pro- etc.) and then -ate Methanol + butanoic acid -> methyl butanoate + water

6. Begins with the prefix from the alcohol (meth-, eth-, pro- etc.) Ends with the prefix from the acid (meth-, eth-, pro- etc.) and then -ate Methanol + butanoic acid -> methyl butanoate + water

7. Begins with the prefix from the alcohol (meth-, eth-, pro- etc.) Ends with the prefix from the acid (meth-, eth-, pro- etc.) and then -ate Methanol + butanoic acid -> methyl butanoate + water

8. In Finnish, it is a bit different: the acid part goes first (in genetive), and then the –ate is replaced by ’esteri’ muurahaishappo + etanoli -> muurahaishapon etyyliesteri + vesi

9. muurahaishappo + etanoli -> muurahaishapon etyyliesteri + vesi methanoic acid ethanol ethyl ester of methanoic acid = ethyl methanoate
