yes, carbon monoxide is a covalent compound between carbon and oxygen
I'm not sure what you mean by "purely covalent", since the ionic-vs-covalent distinction is expressed in terms of electronegativity, which can take a range of values (higher values = more ionic). CO is very much a covalent compound though.
P4O4 is not a chemical compound. P4O10 is a covalent compound. P and O always form covalent bonds.
Yes, CO is a binary compound. It is formed by two different elements. C is Carbon and O is Oxygen. CO is Carbon monoxide.
Yes, carbon (C) and oxygen (O) can form a covalent bond. In covalent bonding, atoms share electrons to achieve a more stable electron configuration, resulting in the formation of a molecule. Carbon and oxygen can share electrons to form molecules like carbon dioxide (CO2) and carbon monoxide (CO).
OCl2 is covalent compound and the bond between O and Cl is covalent
Only in the acid (-COOH) and hydroxy (=C-O-H) group the bonds are polar, all others are covalent.
N2O5 is a covalent compound. It consists of nonmetal atoms (N and O) which typically form covalent bonds by sharing electrons.
P2O5 is covalent compound as the difference in electronegativity between P and O is below 1.7
CH4O, also known as methanol, is a covalent compound. It is composed of nonmetal elements (C, H, and O), which typically form covalent bonds by sharing electrons.
C12H22O11 is a covalent compound. It is composed of nonmetal elements (C, H, O), which typically form covalent bonds by sharing electrons.
The chemical compound P2O2 does not exist. IF it could it would almost certainly be covalently bonded.
OF2 is covalent. Both elements O and F are nonmetals. They would both form negative ions which would not attract each other.
