MCQ
What is the main reason for the fact that carboxylic acids can undergo ionization
  • A
    Absence of $\alpha - $hydrogen
  • ✓
    Resonance stabilisation of the carboxylate ion
  • C
    High reactivity of $\alpha - $hydrogen
  • D
    Hydrogen bonding
✓

Answer

Correct option: B.
Resonance stabilisation of the carboxylate ion
b
Carboxylate acids are easily ionized because there is resonance in carbroxylate ion due to $\pi$ - electron shifting so $H ^{+}$get ionised very easily.
