Question

which of the following is an ionic compound ?​

Answer 1

Sodium chloride, on the other hand, contains ions; it is an ionic compound.Ionic compounds contain ions and are held together by the attractive forces among the oppositely charged ions. ... Molecular compounds contain discrete molecules, which are held together by sharing electrons (covalent bonding).

Answer 2

Sodium chloride, sodium bromide,lithium chloride and lithium bromide are the  ionic compound.

Explanation:

• An ionic compound is composed of cation and anion and by the electrostatic force of attraction.
• But after formation cation attracts the electron pair towards itself and cause some deformation of electron density of anion.
• Above all if the ionic character predominates over covalent character then we call it ionic.
• $NaH$ consist of $Na+$ cations  and $H-$ anions.
•  The bond is purely ionic and the compound is ionic.
