Drawing resonance when comparing acid strength

Postby StephanieDoan3B » Sat Dec 09, 2017 11:54 am

When drawing Lewis structures of HClO, HClO2, HClO3, HClO4 to compare acid strength due to electron withdrawing atoms, do we need to draw all of the resonance structures of HClO4 and HClO3?

Aye fam!

Nah that wouldn't be necessary cuz you just have to recognize that more oxygens would better stabilize the conjugate base, making the acid stronger. You don't need to do resonance anyways as long as you recognize that the double bond character is spread out evenly over the entire molecule. Unless of course of the question asks for multiple lewis structures.
