Question

The ionic bond is absent in

• A. $\mathrm{NaCl}$
• B. $\mathrm{CsCl}$
• C. $\mathrm{LiF}$
• D. ${\mathrm{H}}_2\mathrm{O}$

Answer 1

The correct option is D

${\mathrm{H}}_2\mathrm{O}$

The correct option is (d)

The explanation for the correct option:

• Explanation: Water has a covalent bond between Hydrogen and Oxygen because their electronegativity differences are minor.
  Ionic bonds are electrostatic connections formed by different-charged ions.
  When nonmetals and metals combine, ionic bonds are formed.

The explanation for the incorrect choices:

(a)

• Explanation: Because of its low electronegativity, a metal gives up an electron when forming an ionic bond in order to produce a positive ion or cation.
  Include ionic bonds between electronegative halogen atoms and an extremely electropositive alkali metal.

(b)

• Explanation: Each Cesium ion is coordinated by eight chlorine ions. It acts as a phase-transfer catalyst. It acts as both a phase-transfer catalyst and a vasoconstrictor agent. Cesium chloride is the inorganic chloride salt of Caesium

(c)

• Explanation: They must donate an electron when forming an ionic bond in order to produce a positive ion or cation. Ionic bonds formed between electronegative halogen atoms and a highly electromotive alkali metal.

The correct answer is (d): Water has covalent bonds between hydrogen and oxygen.
