$\text{CH}_3\text{CHCH}\equiv\text{CH}\\\ \ \ \ \ \ \ \ \ |\\ \ \ \ \ \ \ \ \ \text{CH}=\text{CH}_2$
  1. Draw the structure of Pent-4-en-2-ol.
  2. What is nucleophile? Give one example.

Answer

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