IUPAC name of following compound is
2-Aminopentanitrile
3-Aminobutanenitrile
2-Aminobutanitrile
3-Aminopropanenitrile
The Correct Option is B
Approach Solution - 1
The compound shown in the image is:
To find the IUPAC name, follow these steps:
- Identify the Longest Carbon Chain:
- The longest carbon chain contains four carbon atoms. This becomes the parent chain, and it is named "butane".
- Identify the Functional Groups and Their Positions:
- The nitrile group (\(\text{-CN}\)) is present at the end of the chain, making it a butanenitrile.
- An amino group (\(\text{-NH}_2\)) is attached to the third carbon of the chain.
- Name the Compound Using IUPAC Rules:
- The compound is named as an amine with the position indicated: "3-Amino".
- Combining the information, the compound is named 3-Aminobutanenitrile.
- Justify the Answer:
- The presence of both the amino group at position 3 and the nitrile group makes the name "3-Aminobutanenitrile" correct.
- Other options have incorrect positioning or numbering of functional groups.
Thus, the correct IUPAC name is 3-Aminobutanenitrile.
Approach Solution -2
To determine the IUPAC name of the given compound, follow these steps:
Identifying the Main Chain: The longest carbon chain contains four carbon atoms, which is identified as butane.
Locating the Functional Groups: The compound contains a nitrile group (-CN) and an amino group (-NH).
The amino group is located at the third carbon in the chain.
Numbering the Carbon Chain: Number the carbon chain from the end nearest to the functional group:
1 — 2 — 3 — 4
This gives the nitrile group a position of 4 (from the end where it is attached).
Combining the Name: The full name, combining the position of the amino group and the nitrile group, is:
3-Aminobutanenitrile.
Thus, the IUPAC name of the compound is: 3-Aminobutanenitrile.

Solutions
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
For example, salt and sugar is a good illustration of a solution. A solution can be categorized into several components.
Types of Solutions:
The solutions can be classified into three types:
- Solid Solutions - In these solutions, the solvent is in a Solid-state.
- Liquid Solutions- In these solutions, the solvent is in a Liquid state.
- Gaseous Solutions - In these solutions, the solvent is in a Gaseous state.
On the basis of the amount of solute dissolved in a solvent, solutions are divided into the following types:
- Unsaturated Solution- A solution in which more solute can be dissolved without raising the temperature of the solution is known as an unsaturated solution.
- Saturated Solution- A solution in which no solute can be dissolved after reaching a certain amount of temperature is known as an unsaturated saturated solution.
- Supersaturated Solution- A solution that contains more solute than the maximum amount at a certain temperature is known as a supersaturated solution.
