IUPAC name of the following are
`{:(" "CH_(3)),(" |"),(CH_(3)-N-C-CH_(2)-CH_(3)),(" |"" |"),(" "CH_(3)""C_(2)H_(5)):}`

Options

A. 3-dimethylamino-3-methyl pentane
B. 3 (N, N-trimethyl)-3-aminopentane
C. 3, (N, N-trimethyl) pentanammine
D. 3-N, N-dimethyl-3-methyl pentan-3-amine

Answer

To determine the IUPAC name of the given compound, we will follow these steps systematically.

### Step 1: Identify the Functional Group
The compound contains a nitrogen atom (N) bonded to carbon chains, indicating that it is an amine.

**Hint:** Look for the functional group first; in this case, it's an amine due to the presence of nitrogen.

### Step 2: Determine the Longest Carbon Chain
We need to identify the longest continuous carbon chain that is attached to the nitrogen. In this case, we have a 5-carbon chain as the main chain.

**Hint:** Count the number of carbon atoms in the longest chain connected to the nitrogen.

### Step 3: Identify the Substituents
The substituents attached to the nitrogen are two methyl groups (CH₃) and one ethyl group (C₂H₅).

**Hint:** Identify all groups attached to the nitrogen; these will be your substituents.

### Step 4: Number the Carbon Chain
Number the carbon chain starting from the end closest to the nitrogen atom to give the lowest possible number to the nitrogen. In this case, the nitrogen is at position 3 of the 5-carbon chain.

**Hint:** Always number the chain from the end nearest to the functional group for the lowest locants.

### Step 5: Name the Substituents
The substituents are two methyl groups and one ethyl group. Since there are two identical methyl groups, we will use the prefix "di" for the two methyl groups.

**Hint:** Use the appropriate prefixes (di, tri, etc.) for multiple identical substituents.

### Step 6: Combine the Names
The full name will include the position of the nitrogen, the substituents, and the main chain. The order of naming is: substituents in alphabetical order, followed by the parent chain name.

The IUPAC name will be: **3,3-Dimethyl-3-ethylpentan-1-amine**.

### Final IUPAC Name
The final IUPAC name of the compound is **3,3-Dimethyl-3-ethylpentan-1-amine**.
