Polar molecules have an unequal distribution of charge due to the presence of polar bonds or asymmetrical shape, while non-polar molecules have an equal distribution of charge due to the presence of non-polar bonds or a symmetrical shape.
You can determine if a molecule is polar or non-polar by looking at the electronegativity difference between the atoms in the molecule. If the difference is greater than 0.5, the molecule is polar. If the difference is less than 0.5, the molecule is non-polar.
A dipolar moment is a measure of the separation of positive and negative charges in a molecule. It is directly related to the polarity of a molecule, as the larger the dipolar moment, the more polar the molecule is.
Yes, a non-polar molecule can have a dipolar moment if it has bond dipoles that do not cancel out due to the molecule's shape. This is known as a permanent dipole moment.
Understanding polarity and dipolar moment is important in chemistry because it helps predict the physical and chemical properties of molecules, such as solubility, boiling point, and reactivity. It also plays a crucial role in many processes, including biological reactions and intermolecular interactions.
