  • A
    $\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CH}_3$
  • ✓
    $\text{CH}_3​−\text{​C}​−\text{OH}\\ \ \ \ \ \ \ \ \ \ \ \ \ || \\ \ \ \ \ \ \ \ \ \ \ \ \ \text{O}$
  • C
    $ \ \ \ \ \ \ \ \ \ \ \ \text{O}\\ \ \ \ \ \ \ \ \ \ \ \ \ ∣∣\\ \text{CH}_3​−\text{​C}​−\text{OH}$
  • D
    $\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{NH}_2$
✓

Answer

Correct option: B.
$\text{CH}_3​−\text{​C}​−\text{OH}\\ \ \ \ \ \ \ \ \ \ \ \ \ || \\ \ \ \ \ \ \ \ \ \ \ \ \ \text{O}$
Acetic acid $\text{CH}_3​−\text{​C}​−\text{OH}\\ \ \ \ \ \ \ \ \ \ \ \ \ || \\ \ \ \ \ \ \ \ \ \ \ \ \ \text{O}$ has an organic acid functional group.
It is also called ethanoic acid. It can be considered as a compound formed by substituting the hydrogen atom of methane by the carboxylic group $\text{(−COOH)}.$
