Question

Which of the following compounds exhibits ionic bonding?

• A. H\(_2\)O
• B. NaCl
• C. CO\(_2\)
• D. CH\(_4\)

Hint:

In ionic bonding, metals tend to lose electrons and non-metals tend to gain electrons. The electrostatic attraction between the resulting ions forms the bond.

Answer 1

The Correct Option is B

Ionic bonding occurs when electrons are transferred from one atom to another, typically between metals and non-metals. In NaCl (sodium chloride), sodium (Na) donates an electron to chlorine (Cl), forming Na\(^+\) and Cl\(^-\) ions, which are held together by electrostatic forces. This is a classic example of ionic bonding. Thus, the compound that exhibits ionic bonding is NaCl.
