Step 1
All aldehydes have carbonyl carbon bonded to at least two hydrogens. This statement is false. Aldehydes have a carbonyl group (C=O) with one hydrogen atom and one alkyl or aryl group bonded to the carbonyl carbon. The general formula for an aldehyde is RCHO, Show more…

Answer true or false. (a) Carboxylic acids are polar compounds. (b) The most polar bond of a carboxyl group is the $\mathrm{C}-\mathrm{O}$ single bond. (c) Carboxylic acids have significantly higher boiling points than aldehydes, ketones, and alcohols of comparable molecular weight. (d) The low-molecular-weight carboxylic acids (formic, acetic, propanoic, and butanoic acids) are infinitely soluble in water. (e) The following compounds are arranged in order of increasing boiling point:
3. Answer true or false. (3.5 Points) The one aldehyde and the one ketone with a molecular formula of C3H6O are constitutional isomers Aldehydes and ketones both contain a carbonyl group. The carbonyl carbon of a ketone is a stereocenter. Aldehydes and ketones are polar compounds Aldehydes have lower boiling points than alcohols with comparable carbon skeletons Low-molecular-weight aldehydes and ketones are very soluble in water. There is no possibility for hydrogen bonding between molecules of aldehydes and ketones.
