Question

1. Define polar covalent bond ?​

Answer 1

Answer:

Polar Covalent Bonds. A polar covalent bond exists when atoms with different electronegativities share electrons in a covalent bond.The unequal sharing of the bonding pair results in a partial negative charge on the chlorine atom and a partial positive charge on the hydrogen atomA covalent bond that has an unequal sharing of electrons, as in part (b) of Figure 4.4. 1, is called a polar covalent bond. A covalent bond that has an equal sharing of electrons is called a nonpolar covalent bond.

Hope this helps you

Answer 2

polar covalent bounds of Polar covalent boud exists when atoms with the different electro negativties shat electron is a covalent boud as in part of figure 4.41 is called a polar covalent bond
