True or fasle. An aldehyde functional group must be on the outside of a molecule while the ketone functional group must be inside a molecule.

In what way is an aldehyde functional group different from that of a ketone?

What is the functional group of propanoic acid? How do we know if it's soluble in water or insluble in water using the flowchart that is attached. which test should be performed using the flowchart. Is propanoic acid a ketone, aldehyde, ester or alcohol and how did you know?what would be the most efficient series of solubility and functional group tests that would identify the functional group? Also what could be the sources of error in this experiment? What could occur that would give false positives, false negatives, or incorrect interpretations?

Both aldehydes and ketones contain carbonyl groups. In aldehydes, the carbonyl carbon atom is bonded to a hydrogen atom, whereas in ketones, the carbonyl carbon atom is bonded to another carbon atom. Select the true statements about aldehydes and ketones.   - Ketones have lower boiling points than alcohols of similar size. - Aldehydes contain a carbon–oxygen double bond. - Butanal has a higher boiling point than 2-butanol. - Aldehydes with more than five carbon atoms are soluble in water, but not organic solvents. - Both aldehydes and ketones can hydrogen bond with water molecules. - Propanal is a gas at room temperature, whereas formaldehyde (methanal) is a liquid at room temperature.
