the naming of an ester is done by combining the names of the two components of which it is comprised. the first part of the name comes from which of the following?
select the correct answer below:
the first part of the name comes from the carbonyl group in the ester.
the first part of the name comes from the acid portion of the ester.
the first part of the name comes from the total number of carbons in the ester.
the first part of the name comes from the alcohol portion of the ester.

Explanation:

Esters are named by combining the name of the alcohol (which gives the first part of the name, usually as an alkyl group) and the name of the acid (with the -ic acid ending changed to -ate). For example, ethyl acetate is made from ethanol (alcohol) and acetic acid. The "ethyl" part (from ethanol) is the first part of the name.

Answer:

The first part of the name comes from the alcohol portion of the ester.
