Answer
- $\text{CH},-\stackrel{3\ \ \ \ \ }{\text{CH}}-\stackrel{4\ \ \ \ \ }{\text{CH}}\equiv\stackrel{5 \ \ \ \ }{\text{CH}}\\\ \ \ \ \ \ \ \ \ \ \ \ |\\\ \ \ \ \ \ \ \ \ \ \ \text{CH}=\text{CH}_2\\\ \ \ \ \ \ \ \ \ \ ^{{\ \ 2\ \ \ \ \ \ \ \ \ \ \ \ \ \ 1}}\\ \ \ \ \ \ \ \ ^{\text{3-methyl pent-1-en-4yne}}$
- $\stackrel{1\ \ \ \ \ }{\text{CH}_3}-\stackrel{2\ \ \ \ }{\text{CH}}-\stackrel{3\ \ \ \ \ }{\text{CH}}-\stackrel{4\ \ \ \ }{\text{CH}}=\stackrel{5 \ \ \ \ \ }{\text{CH}_2}\\\ \ \ \ \ \ \ \ \ \ \ \ \ \ |\\\ \ \ \ \ \ \ \ \ \ \ \ \ \text{OH}$
- Nucleophile is a species which is either negatively charged or has lone pair of electron.
