Which one of the following orders of acid strength is correct

A.RCOOH > HC CH > HOH > ROH

B.RCOOH > ROH > HOH > HC CH

C.RCOOH > HOH > ROH > HC CH✓ Correct

D.RCOOH > HOH > HC CH > ROH

Explanation

Order of acidity is given below: RCOOH HOH ROH HC CH The carboxylic acid is the most acidic because the carboxylate ion is the most stable by resonance. And the acidic strength depends on the conjugate base of the compound. The acid strength is opposite of the conjugate basic strength. The basic strength is given below: C CH R O OH RCOO
