Give two names for each of the following nitriles:

It is a method to give a scientific name to the organic compounds recommended by the International Union of Pure and Applied Chemistry.

IUPAC rules used for naming of nitrile

• Name the parent chain

• Assign numbering to the substituents

• Assign the first number to the bulky group

• nitrile gets the first priority

• Write the name of the molecule in alphabetic

• Suffix nitrile is used

The compound has 4 carbon so the parent chain is butane and the nitrile group is present at the 1stposition so the name is butane nitrile.

As per the molecule select the longest carbon chain that is of 5 carbon so that the parent chain is pentane and the methyl substituent is present at 4thposition and the nitrile gets 1st position so the naming is 4-methyl pentane nitrile.
