HNO2 is a molecular compound. It consists of covalent bonds between the nitrogen, hydrogen, and oxygen atoms, rather than ionic bonds typically found in ionic compounds.
Nitrous acid HNO2 cannot be isolated as a pure compound. In the gas phase molecules of HNO2 are covalently bonded. In water it is a weak acid forming the nitrite ion however it readily disproportionates:- 3HNO2 -> H3O+ + NO3- + NO
H2O is a molecular compound.
HCIO4 is an ionic compound.
NO is a molecular compound, not an ionic compound. It is made up of individual atoms of nitrogen and oxygen that are covalently bonded together.
Sodium chloride (NaCl) is an ionic compound.
