Chapter B, Problem B.45P

Interpretation Introduction

(a)

Interpretation:

The structure for $\text{3-phenylmethylhex-4-en-1-yne}$ is to be drawn.

Concept introduction:

Commonly used trivial names for substituents having $\text{C=C or C}\equiv \text{C}$ are used when writing the name of a molecule. The root is named considering the longest continuous chain of carbon atom or the largest ring. The substituents are written with appropriate locator numbers and trivial names. Benzene derivatives are named by considering the root as benzene. If the substituents attached to a benzene ring are complicated, it is easy to treat the benzene ring as a substituent instead of a root. These substituents are incorporated into the IUPAC name.
