- Why does benzene show electrophilic substitution easily?
- Complete the following:
✓
Answer
- $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{COONa}$ (sodium propanoate), on electrolysis will give butane.
- It is because benzene has $6\pi$ electrons, therefore, it attracts electrophile and undergo electrophilic substitution reactions.
- $\text{CH}_3-\text{C}=\text{CH}_2+\text{H}_2\text{O}\xrightarrow{\text{H}^+}\\ \ \ \ \ \ \ \ \ \ \ \ \ \ |\\ \ \ \ \ \ \ \ \ \ \ \ \ \text{CH}_3\\ \ \ \ \ \ _{2-\text{Methyl propene}}\\ \ \ \ \ \ \ \ \ \ \ \ \ \text{OH}\\ \ \ \ \ \ \ \ \ \ \ \ \ \ |\\ \text{CH}_3-\text{C}-\text{CH}_3\\ \ \ \ \ \ \ \ \ \ \ \ \ \ |\\ \ \ \ \ \ \ \ \ \ \ \ \ \text{CH}_3\\ \ \ \ \ \ _{2-\text{Methyl propan-2-ol}}$
