Question

Explain with suitable example polar covalent bond

Answer 1

In polar covalent compounds one element is more electronegative than other and the more electronegative element gain electron from less electronegative element .+,-charges appear on both elements .e.g NaCl

Answer 2

❤. POLAR COVALENT BOND:

• A covalent bond formed between two non-metal atoms of different elements is called polar covalent bond.
• In these bonds, the electrons are shared unequally and the bonded atoms acquire a partial positive charge and negative charge.
• Ex:The bond in HF is Polar covalent bond.

$\large\star\mathfrak\blue{{EXPLANATION....!! }}$

• Since Fluorine has high electronegativity, the electronegativity of Fluorine is greater than that of hydrogen.
• Thus in HF bond, the Fluorine end is negative whereas hydrogen end is positive.
• Hence the bond in HF is a polar covalent bond.
