Question

Write the structure of the following organic halogen compound.$2-(2-\mathrm{chlorophenyl})-1-\mathrm{iodooctane}$

Answer 1

IUPAC rule:

• IUPAC is the International Union for Pure and Applied Chemistry.
• It is a worldwide using chemical names that follow certain rules.

Structure:

Step 1: Finding the longest chain and number of carbon atom

• Here, there is eight carbon which is arranged linearly.

$\mathrm{C}-\mathrm{C}-\mathrm{C}-\mathrm{C}-\mathrm{C}-\mathrm{C}-\mathrm{C}-\mathrm{C}$

Step 2: Finding and positioning substituents.

• $2-(2-\mathrm{chlorophenyl})$ indicates the phenyl group is attached to the second position of the carbon chain and the chloro group is attached to the second carbon of the phenyl ring.
• In the ${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{Cl}$ group, the chloro group is attached at the second position to the phenyl group.

$$\begin{gathered} \mathrm{C}-\underset{|}{\mathrm{C}}-\mathrm{C}-\mathrm{C}-\mathrm{C}-\mathrm{C}-\mathrm{C}-\mathrm{C} \\ {\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{Cl}}^{} \end{gathered}$$

• $1-$Iodo octane indicates the iodine group is attached to the first carbon.

$$\begin{gathered} \mathrm{I}-\mathrm{C}-\underset{|}{\mathrm{C}}-\mathrm{C}-\mathrm{C}-\mathrm{C}-\mathrm{C}-\mathrm{C}-\mathrm{C} \\ \underset{}{{\mathrm{C}}_6{\mathrm{H}}_5\mathrm{Cl}} \end{gathered}$$

Step 3: Satisfying the valency of carbon.

• On satisfying the valency of carbon with hydrogen the structure of the compound will be
