Question

In which of these organic compounds is an oxygen atom double bonded to a carbon somewhere other than the end of a carbon chain?

alkane
alcohol
ketone
aldehyde

Answer 1

Poorly worded question. Ketone and aldehyde are my choices. However, an alcohol can also be an answer, but a think the author of the question is referring to the functional group it's self. Carboxylic acid is an alcohol that also has a c=o bond, which is why this a poorly worded question in my opinion.

Answer 2

Does this mean I should choose alcohol?

Answer 3

No. I told you which ones were my choices.
