Arrange in their increasing acid strength
H2o , C2H5OH , C6H5OH , C6H5COOH
Answers
The correct answer to the increasing order of the acidic strengths of the given compounds is - HCOOH > CH₃COOH > CH₃CH₂COOH.
The strengths of the carboxylic acids are known to vary based on the total power to withdraw electrons of the atoms that are bonded to the carboxyl group. When the substituent group has more electron-withdrawing power, the stronger will be the acid. The acidic strength is decreased by the electron-releasing group. This is because the release of protons gets hindered.
Although all are weak acids, the CH₃ group has a lesser electron-withdrawing power than H. So, CH₃COOH is comparatively a weaker acid than HCOOH. Similarly, CH₃CH₂COOH is a much weaker acid than CH₃COOH and HCOOH.
