The molecule below contains both an aldehyde and a ketone functional group. select only the carbonyl carbon atom of the aldehyde functional group. identify the carbon atom by selecting the atom and assigning it a map number of 1. to do this, right-click on an atom and choose atom properties.

Carbonyl compounds are those compounds in which carbon aton is doubly bonded to oxygen atom.

The hybridization of carbon and oxygen in carbonyl compounds is Sp². Folowing are examples of carbonyl compounds,

1. Ketones

2. Aldehydes

3. Carboxylic Acids

4. Acyl Halides

5. Amides

6. Esters

7. Anhydrides e. t. c

Result:

In given the structure the carbonyl groups are highlighted RED, as shown below.
