Detailed Solution

The above statement is false.
The IUPAC system does not recognize the prefix n-. As a result, the correct name for

{CH}_{3} - {CH}_{2} - {CH}_{2} - {CH}_{3}

is butane; n-butane is its popular name, but it is now also acceptable to the IUPAC system. The International Union of Pure and Applied Chemistry is abbreviated as IUPAC.
The correct statement would be, “The correct IUPAC name of

{CH}_{3} - {CH}_{2} - {CH}_{2} - {CH}_{3}

is butane”.
