Question

IUPAC name of following compound is

• A. 2-Aminopentanitrile
• B. 3-Aminobutanenitrile
• C. 2-Aminobutanitrile
• D. 3-Aminopropanenitrile

Answer 1

Answer: (B)

3-Aminobutanenitrile

Answer 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.
