Is so2 an ionic or covalent compound?
It form. Covalent bond because Each oxygen atom shares two valence electrons with sulfur. SO2 is covalent since it is formed by the sharing of electrons between sulphur and oxygen.
- Sodium chloride is an ionic compound. Many bonds can be covalent in one situation and ionic in another. For instance, hydrogen chloride, HCl, is a gas in which the hydrogen and chlorine are covalently bound, but if HCl is bubbled into water, it ionizes completely to give the H+ and Cl- of a hydrochloric acid solution.
- MgS is formed by the reaction of sulfur or hydrogen sulfide with magnesium. The chemical properties of MgS resemble those of related ionic sulfides such as those of sodium, barium, or calcium. It reacts with oxygen to form the corresponding sulfate, magnesium sulfate.
- Hydrogen chloride gas and hydrochloric acid have the same chemical formula, HCl. The difference between the two is that hydrogen chloride is a gas, and hydrochloric acid is an aqueous solution. Hydrogen chloride gas is heavier than air, slightly yellow in color, non-flammable, and highly reactive with water.
The hydrogen chloride molecule HCl is a simple diatomic molecule consisting of a hydrogen atom H and a chlorine atom Cl connected with a covalent single bond. Since the chlorine atom is much more electronegative than the hydrogen atom, the covalent bond between the atoms is quite polar.
- Hydrogen has an electronegativity of 2.1, and chlorine has an electronegativity of 3.0. The electron pair that is bonding HCl together shifts toward the chlorine atom because it has a larger electronegativity value. A bond in which the electron pair is shifted toward one atom is called a polar covalent bond.
- Hydrogen Chloride
- Solubility in Aqueous HCl. If your unknown is not soluble in water, but does dissolve in 5% HCl, then your unknown probably contains a basic functional group that is protonated by the hydrochloric acid producing an ionic compound. The most common organic functional group with this property is an amine (Scheme 4).
