Question

Identify the correct IUPAC name for $\left(C{H}_3{)}_{3}CC{H}_{2}C{H}_{2}CH\right(C{H}_3)CN$.

• A. 2,5,5-trimethylhexane-1-nitrile
• B. 2,5,5,5-tetramethylpentanenitnle
• C. 2-cyano-5,5-dimethylhexane
• D. 2-cyano-5,5,5-tetramethylpentane

Answer 1

The correct option is A 2,5,5-trimethylhexane-1-nitrile

The correct IUPAC name for $\left(C{H}_3{)}_{3}CC{H}_{2}C{H}_{2}CH\right(CN)C{H}_3$ is 2,5,5-trimethylhexanenitrile.
It is a cyanide and the parent chain contains six carbon atoms.
Three methyl groups are present as substituents. One at second carbon and two at fifth carbon atom.
