Question

The nature of bonds present in sodium hydroxide include

• A. Ionic, covalent and coordinate covalent
• B. Ionic and covalent
• C. Covalent and coordinate covalent
• D. Ionic and coordinate covalent

Answer 1

The correct option is B

Ionic and covalent

Explanation for Correct option:

In Sodium hydroxide($NaOH$), an ionic bond is formed between $N{a}^{+}andO{H}^{-}$and a covalent bond is formed between O and H.

Explanation for Incorrect options:

Ionic bond occurs when oppositely charged ions come together. Positive ions attract negative ions, or we can say that anions and cations have an electrostatic attraction.

A covalent bond is a chemical bond formed when two atoms share their unpaired electrons.

A co-ordinate bond, on the other hand, is a type of covalent bonding in which just one atom gives electrons to form the bond. Nothing is contributed by the other atom.

A) Ionic, covalent and coordinate covalent- coordinate covalent bond is not present in sodium hydroxide.

C) Covalent and coordinate covalent- coordinate covalent bond is not present in sodium hydroxide.

D) Ionic and coordinate covalent- coordinate covalent bond is not present in sodium hydroxide.

Hence, the correct option is (B). Sodium hydroxide contains Ionic and covalent bonds.
