Question

Polar covalent bond is present in:

• A. H\(_2\).
• B. O\(_2\).
• C. HCl.
• D. N\(_2\).

Hint:

A polar covalent bond results from unequal sharing of electrons due to a difference in electronegativity between the atoms involved.

Answer 1

The Correct Option is C

Step 1: Understanding polar covalent bonds.
A polar covalent bond occurs when two atoms with different electronegativities form a bond, resulting in an unequal sharing of electrons. Step 2: Explanation.
In HCl (hydrogen chloride), chlorine is more electronegative than hydrogen, so the electrons in the bond are more attracted to chlorine, creating a partial negative charge on chlorine and a partial positive charge on hydrogen. Step 3: Conclusion.
Thus, HCl has a polar covalent bond due to the difference in electronegativity between hydrogen and chlorine.
