COMPOUNDS
Answer:
a) Ethyl butanoate
- H3C – CH2 – CH2 – COO – CH2 – CH3
The COO between two carbons allows identifying that the compound is an ester;
Thus, the nomenclature for esters is rad1 + rad2 act + ila;
rad1 is butane because there are 4 carbons up to the function carbon;
rad2 is et because there are 2 carbons after the oxygens.
b) Pentan-1-al
- CH3 – CH2 – CH2 – CH2 – COHO OH
at the end of this chain it turns out to be an aldehyde, because the carbon does not have more hydrogens, only the OH;
Thus, he makes a double bond with O and a single bond with H;
The nomenclature for aldehyde is to add AL at the end of the compound;
The radical is pentan because the chain has 5 carbons and no unsaturation;
The 1 serves to indicate where the aldehyde function group is.
Esters
- It results from the reaction of a carboxylic acid with an alcohol, eliminating water.
Aldehydes
- Body formed by the dehydrogenation or oxidation of an alcohol.
