Explanation:

1. Aldehydes have a carbonyl group ($\text{-CHO}$) at the end of a carbon chain, bonded to one alkyl group and one hydrogen.
2. Ketones have a carbonyl group ($\text{C=O}$) bonded to two alkyl groups, located in the middle of a carbon chain.
3. Neither includes compounds with no carbonyl group, or carbonyl groups in other functional classes (ethers, alcohols, alkenes).

Answer:

Aldehyde:

$\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}=\text{O}$

Ketone:

$\text{CH}_3\text{CH}_2\text{C(=O)CH}_3$

Neither:

$\text{CH}_3\text{CH(OH)CH}_3$, $\text{CH}_3\text{OCH}_2\text{CH}_3$, $\text{CH}_3\text{CH=CHCH}_3$, $\text{CH}_3\text{CH(CH}_3\text{)CH=CH}_2$
