homework help 1005

There are four isomeric esters with the formula ##”C”_4″H”_8″O”_2##.

First, draw all the esters of a one-carbon acid. These are

Propyl formate

##”HCOOCH”_2″CH”_2″CH”_3##

and

Isopropyl formate

##”HCOOCH”(“CH”_3)_2##

Then draw all the esters of a two-carbon acid:

Ethyl acetate

##”CH”_3″COOCH”_2″CH”_3##

Finally, draw all the esters of a three-carbon acid:

Methyl propionate

##”CH”_3″CH”_2″COOCH”_3##

And that’s it!
