What is polar covalent bond??
Dear student,
The covalent bond between two atoms with different electronegativities is called a polar covalent bond. Due to different electronegativities, the less electronegative atom acquires a partial positive charge and the more electronegative atom acquires a partial negative charge and thus the compound becomes polar. Example: HCl, H2O

In the following example, the green circle is an oxygen atom and the blue circles are hydrogen atoms. Due to the lone pair of electrons, the water molecule takes an angled shape and the difference in the electronegativities makes the oxygen atom partially negative.
