Question

What are the covalent bonds that form between atoms of different electronegativities called?

a. pure bonds
b. ionic bonds
c. polar bonds
d. uneven bonds

Answer 1

The covalent bonds that form between atoms of different electronegativities called polar bonds. Just like in water. The cause of polarity in water molecules is because of the high electronegativity difference between oxygen and hydrogen.

Answer 2

Answer: c. polar bonds

Step-by-step explanation:

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. It is also defined as the bond which is formed due to the unequal sharing of electrons between the atoms.

Ionic bond is formed when there is complete transfer of electron from one atom to another atom.

Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms. It is also defined as the bond which is formed due to the equal sharing of electrons between the atoms.

Hence, the correct answer is polar bonds.
