Which is correctly matched with IUPAC Name ?

Options

A. `2-`Nitrocyclohex`-5-`ene`-1-`carbaldehyde
B. `5-`Chloro`-3-`hydroxycyclohexane`-1-`carboxylic acid
C. `2-`Ethenyl`-6-`chlorocyclohexanol
D. `2-(2-`bromocyclohexyl)propanenitrile

Explanation

To determine which compound is correctly matched with its IUPAC name, we need to analyze the given options and identify the correct IUPAC nomenclature for the compounds. Here’s a step-by-step solution:

### Step 1: Identify the Compounds
We have four compounds with their respective IUPAC names. We need to analyze each compound to see if the IUPAC name corresponds correctly.

### Step 2: Determine the Parent Chain
For each compound, identify the longest carbon chain that contains the highest priority functional group. In this case, we are looking for the nitrile group (–C≡N) as the main functional group.

### Step 3: Number the Carbon Chain
Number the carbon atoms in the parent chain starting from the end nearest to the functional group to ensure that the functional group gets the lowest possible number.

### Step 4: Identify Substituents
Look for any substituents attached to the parent chain. In this case, we have a bromine substituent and a cyclohexyl group.

### Step 5: Assign Numbers to Substituents
Assign numbers to the substituents based on their position on the carbon chain. The numbering should be such that the substituents receive the lowest possible numbers.

### Step 6: Write the IUPAC Name
Combine the names of the substituents with the name of the parent chain and the functional group. The substituents are listed in alphabetical order, and their positions are indicated by the numbers assigned.

### Step 7: Compare with Given Options
Now, compare the IUPAC name you derived with the names provided in the options.

### Conclusion
After analyzing the compound as described, we find that the correct IUPAC name is **2,2-bromo-cyclohexyl-propane-nitrile**, which corresponds to option D.
