Step 1:I'm here to help! I see that you've provided a table containing some chemical compounds and asked for their names.
However, you didn't mention which compound corresponds to which name. I'll assume that the first column represents the structural formula of the compound, and the second column is the name that you want me to fill in. Since there are no images or additional information provided, I will solve this problem based on the structural formulas given. I will use the rules of nomenclature for organic chemistry to name each compound.
Step 2:
For the first compound, CH^3CH^2CH^3, it is a straight-chain alkane with 3 carbon atoms. Its name is propane. \text{CH}_3\text{CH}_2\text{CH}_3 \longrightarrow \boxed{\text{propane}}
Step 3:
The second compound, CH^3—CH—CH^3, is a straight-chain alkane with 3 carbon atoms but has a single carbon-carbon bond between the second and third carbon atoms. This makes it a substituted alkane with a methyl group (—CH3) attached to the central carbon atom. Its name is isobutane. \text{CH}_3\text{—CH—CH}_3 \longrightarrow \boxed{\text{isobutane}}
Step 4:
The third compound, CH^3CH^2CH^2CH^2CH^3, is a straight-chain alkane with 5 carbon atoms. Its name is pentane. \text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_3 \longrightarrow \boxed{\text{pentane}}
Step 5:
The fourth compound, CH^3CH^2CH^2CH^2CH^2CH^3, is a straight-chain alkane with 6 carbon atoms. Its name is hexane. \text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_3 \longrightarrow \boxed{\text{hexane}}
Final Answer
The names of the given compounds are: 1. propane 2. isobutane 3. pentane 4. hexane
