Calculate Molecular Polarity



Formula

The formula to calculate the Molecular Polarity is:

\[ \text{MP} = \sum (\Delta EN \times d) \]

What is Molecular Polarity?

Molecular polarity refers to the distribution of electric charges in a molecule, which determines how a molecule interacts with other substances. It arises due to the difference in electronegativity between atoms in a molecule, where one atom might pull electrons more strongly than another, creating a dipole moment. This results in one part of the molecule having a slightly negative charge and another part having a slightly positive charge. The polarity of a molecule influences its physical properties such as boiling and melting points, solubility, and reactivity.

Example Calculation

Let's consider an example:

Using the formula to calculate the Molecular Polarity:

\[ \text{MP} = 1.5 \times 0.1 = 0.15 \text{ D} \]

This means that the Molecular Polarity (MP) is 0.15 D.
