which compound contain both ionic and covalent bond? a.ammonia b.ammonia chloride c.hydrogen chloride d.sodium chloride?

The option b should be "ammonium chloride" instead of "ammonia chloride".

The answer is : b. ammonium chloride

a. Ammonia, NH₃, is molecular. In NH₃ molecule, the N atom links the three H atoms by covalent bonds. There is no ionic bond.

b. Ammonium chloride, NH₄Cl, is an ionic compound in which NH₄⁺ and Cl⁻ ions are held together by ionic bond. In NH₄⁺ ion, the N atom links the four H atoms by covalent bonds.

c. Hydrogen chloride, HCl, is molecular. In HCl molecule, the H atom and Cl atom are linked together by covalent bond. There is no ionic bond.

d. Sodium chloride, NaCl, is an ionic compound in which Na⁺ and Cl⁻ ions are held together by ionic bond. There is no covalent bond. There is no covalent bond.
