It is an ionic compound
The compound is ethanol and is a covalent compound.
That compound is methanol and is a molecular compound. All bonds in this compound are covalent.
Only in the acid (-COOH) and hydroxy (=C-O-H) group the bonds are polar, all others are covalent.
iron being highly electropositive it does not react with covalent compound formed by two electropositive elements. that is tin nitride.
Iron(III) chloride is an ionic compound.
Covalent compound
Yes. Dextrose does not dissociate in water, and therefore does not release ions.
