Molecules possessing polar covalent bonds are called dipoles.Question 23Answera.Falseb.True

The statement "Molecules possessing polar covalent bonds are called dipoles" is true, but with a caveat.

Here's why:

A molecule that possesses polar covalent bonds can be a dipole if the shape of the molecule does not cancel out the bond polarities. A polar covalent bond is a type of chemical bond where a pair of electrons is unequally shared between two atoms, which creates a dipole (a separation of positive and negative charge).

However, not all molecules with polar covalent bonds are dipoles. The overall polarity of a molecule also depends on its shape. For example, carbon dioxide (CO2) has polar covalent bonds, but it is not a dipole because it is a linear molecule and the bond polarities cancel each other out.

So, while it's true that molecules with polar covalent bonds can be dipoles, it's not accurate to say that all such molecules are dipoles.

So, the correct answer is b. True, but with the understanding that the molecule's shape can influence whether it is a dipole or not.
