H2 and a polyatomic ion
e.g.) H2CO3 (carbonic acid)
hope that helps:)
Fluorine can not form oxyacids because fluorine is more electronegative than oxygen, and oxyacids are formed only from elements that are less electronegative than oxygen.
aluminium is passive towards oxyacids due to formation of protevtive layer of oxide. this protective layer resists the contact of aluminium with water or oxygen thatswhy aluminium is passive towards oxyacids
Oxyacids of iodine are:- iodic acid: HIO3- iodous acid: HIO2- hypoiodous acid: HIO- ortho periodic acid: HIO4- meta periodic acid: H5IO6
HCl4(AQ)
in my opinion flourine is very electronegative and it cannot exist in positive oxidation states in its compounds .in oxyacids of halogens ,oxygen carries a negative charge while the halogen carries a positive charge.the electronegativity of flourine is 4,while that of oxygen is 3.5. so due to high value of electronegativity ,flourine shows reluctance to form positive oxidation states and donot form oxyacids........

The strength of oxyacids generally increases with the number of oxygen atoms bonded to the central atom and the electronegativity of that central atom. More oxygen atoms can stabilize the negative charge of the conjugate base after proton donation, while a more electronegative central atom can better stabilize the negative charge. For example, in the series HClO, HClO2, HClO3, and HClO4, the acid strength increases due to the increasing number of oxygen atoms. Thus, oxyacids can be ranked from weakest to strongest based on these factors.
Fluorine does not naturally form oxyacids because it is the most electronegative element and cannot easily lose electrons to form a stable positive oxidation state. This makes it challenging for fluorine to form covalent bonds with oxygen in a way that would lead to the formation of oxyacids.
Acids that have three or more elements are called oxoacids or ternary acids. These acids contain hydrogen, oxygen, and at least one other element. Examples include sulfuric acid (H2SO4) and phosphoric acid (H3PO4).
