Chapter 17.5, Problem 13P

(a)

Interpretation Introduction

Interpretation:

It should be determined that how the given $\text{1-}$ pentyn $\text{-3-}$ ol is prepared using ethyne as starting material and why ethyne slkylated before nucleophilic addition.

Concept Introduction:

Systematic Name: It is a standardized name given for a chemical compound in systematic manner.  Any organic molecule can be named by using IUPAC (International Union for Pure and applied chemistry) rules.  IUPAC name consists of three parts in major namely Prefix suffix and root word.

The IUPAC nomenclature of Acetylene is ethyne. The molecular formula of ethyne is ${\text{C}}_{\text{2}}{\text{H}}_{\text{2}}$.

It is an alkyne and it can undergo substitution reaction.

Nucleophile: donates pair of electrons to positively charged substrate resulting in the formation of chemical bond.
