Why sodium hydroxide is good example of both ionic and covalent bond may exist in one compound?

Answer 1

Sodium hydroxide is a good example of a compound with both ionic and molecular bonds because the bond between the sodium ion and hydroxide ion is ionic, but the bond between the oxygen atom and the hydrogen atom in the hydroxide ion itself is covalent. Sodium hydroxide is typically referred to as an ionic compound because the ionic bond dominates its chemistry.

Answer 2

Sodium hydroxide is a good example because it contains both ionic and covalent bonds. The bond between sodium and hydroxide is ionic, where sodium donates an electron to oxygen. The bond within the hydroxide ion itself (O-H bond) is covalent, where the electrons are shared between oxygen and hydrogen atoms.
