Give the structural formulate and IUPAC names of the following compounds: (i) N, N-diethyl butyl amine. (ii) Allyl aine.

To tackle the structural formulas and IUPAC names of the compounds you've mentioned, let's break them down one by one. Understanding the structure of organic compounds is crucial for grasping their properties and reactivity.

N, N-Diethylbutylamine

This compound is an amine, which means it contains a nitrogen atom bonded to carbon atoms. The name "N, N-diethylbutylamine" indicates that there are two ethyl groups attached to the nitrogen atom and a butyl group attached to the carbon chain.

Structural Formula

The structural formula can be represented as follows:

• Start with the butyl group: CH₃–CH₂–CH₂–CH₂–
• Add the nitrogen atom: N
• Attach two ethyl groups to the nitrogen: CH₃–CH₂– and CH₃–CH₂–

Putting it all together, the structural formula looks like this:

       CH2CH3
         |
CH3-CH2-N-CH2CH3
         |
       CH2-CH2-CH2-CH3

IUPAC Name

The IUPAC name for this compound is indeed N,N-diethylbutan-1-amine. The "butan-1" indicates that the butyl group is at the first carbon of the butane chain, and the "N,N-diethyl" specifies the two ethyl groups attached to the nitrogen.

Allylamine

Next, let's look at allylamine, which is a simpler compound. It consists of an amine group attached to an allyl group, which is a three-carbon chain with a double bond.

Structural Formula

The structural formula for allylamine can be described as follows:

• Start with the allyl group: CH₂–CH=CH₂
• Add the amine group: –NH₂

When combined, the structural formula appears as:

    H2C=CH-CH2-NH2

IUPAC Name

The IUPAC name for this compound is simply 2-propen-1-amine. The "2-propen" indicates the presence of a double bond between the second and third carbon atoms, and the "1-amine" signifies the amine group is attached to the first carbon.

Summary

In summary, we have:

• N,N-Diethylbutylamine: Structural Formula: CH₃–CH₂–N(CH₂CH₃)₂–CH₂–CH₂–CH₂–; IUPAC Name: N,N-Diethylbutan-1-amine
• Allylamine: Structural Formula: H₂C=CH–CH₂–NH₂; IUPAC Name: 2-propen-1-amine

Understanding these structures and names helps in recognizing the functional groups and predicting the behavior of these compounds in chemical reactions.
