guyz how arrange the acid strength and basic strength of given aryl halides ,phenols,ethers in increasing and decreasing order ??

Hello Chetan

The strengths of  carboxylic acids are known to vary based on the total power to withdraw electrons of the atoms that are bonded to the carboxyl group.

Ex:  CH group has a lesser electron-withdrawing power than H. So, CHCOOH is comparatively a weaker acid than HCOOH. Similarly, CHCHCOOH is a much weaker acid than CHCOOH and HCOOH.
