Question

give the iupac name for each of the following structures:

Explanation:

Step1: Identify the parent - chain

For each structure, first find the longest continuous carbon - chain containing the highest - priority functional group.

Step2: Number the carbon atoms

Number the carbon atoms in the parent - chain starting from the end that gives the substituents the lowest possible numbers.

Step3: Name the substituents

Name the substituents attached to the parent - chain (e.g., methyl ($-CH_3$), fluoro ($-F$), bromo ($-Br$), iodo ($-I$)).

Step4: Indicate the position of substituents

Use the carbon - atom number to indicate the position of each substituent.

Step5: Name the parent - chain

Name the parent - chain based on the number of carbon atoms (e.g., methane for 1 C, ethane for 2 C, propane for 3 C, etc.) and the presence of double or triple bonds (alkene for double bond, alkyne for triple bond).

Step6: Combine the names

Write the name of the substituents in alphabetical order followed by the name of the parent - chain.

Answer:

1. Heptane
2. 3,5 - Dimethylheptane
3. 6 - Fluoro - 2 - methylheptane
4. 4 - Bromo - 3 - fluoro - 1 - pentene
5. (E) - 1 - Iodo - 2 - butene
6. 1 - (Cyclopenten - 1 - yl)ethane
7. 1 - (1,1 - Dimethylethyl)cyclobutene
8. 4 - Chloro - 1 - butyne
9. 1,2,4,5 - Tetramethylbenzene
10. 1,4 - Dibromobenzene
