What are saturated compounds? Identify the ketone and its molecular formula from the given options.

here are the solutions to your questions:

2.1. A saturated compound is an organic compound that contains only single bonds between carbon atoms. All carbon atoms are bonded to the maximum number of hydrogen atoms possible.

2.2.1. A compound with a carbonyl group bonded to two carbon atoms is a ketone. Compound E, $\text{CH}_3\text{COCH}_2\text{CH}_2\text{CH}_3$, is pentan-2-one, which is a ketone. The carbonyl carbon is bonded to a methyl group and a propyl group.

$$\boxed{\text{E}}$$

2.2.2. Compound E has the molecular formula $\text{C}5H{10}\
