The functional group contained in the compound

O
||
CH_3-C-O-CH_3

is a(n).

A)carboxy
B)amine
C)ester
D)amide

The first O is connected to the second C with a double bond.

The underscore means subscript.

I assume that is CH3COOCH3. That is an ester.

RCOOH acid
RCOOCH3 ester
RCH2NH2 amine
RCH3CONH2 amide (a primary amide in this case)

So the answer would be an ester since it would be the functional group?

yes

Thank You.

You guys never get enough credit for all the help you give.

So Thank You once again I really appreciate it.

You're welcome. Besides helping someone who needs help we get to exercise our brain and that keeps us running. Also, I like to think that it will delay the onset of diseases such as Alzheimer's etc.

To identify the functional group contained in the given compound, you need to understand the structure and properties of different functional groups.

Looking at the given compound, CH3-C-O-CH3, we see that there is an oxygen atom bonded to a carbon atom present in the middle of the chain. This oxygen atom is double-bonded to a carbon atom on one side and single-bonded to another carbon atom on the other side. This arrangement of atoms indicates the presence of an "ester" functional group.

An ester is a class of organic compounds that has a carbon atom double-bonded to an oxygen atom, which is then bonded to another carbon atom (known as the "acyl" group). Esters are commonly formed by the reaction between an alcohol and an acid. In the given compound, the acyl group is represented by R-C=O and is attached to the two methyl (CH3) groups.

Therefore, the functional group contained in the given compound is a C)ester.
