Molecular polarity

• Polar molecules arise when there is an uneven distribution of electron density due to differences in electronegativity between atoms, resulting in a slight positive charge on one side of the molecule and a slight negative charge on the other.
• One approach to determining molecular polarity is by examining the molecule's symmetry.
• If a molecule is symmetric and all atoms have the same electronegativity, it is likely nonpolar.
• , if a molecule is asymmetrical or contains different atoms, it is more likely to be polar.
• Another important factor in determining molecular polarity is the molecular geometry.
• Experimental techniques such as spectroscopy and molecular dipole moment measurements can provide quantitative evidence of a molecule's polarity.
• , where knowledge of a molecule's polarity can help determine its solubility and ability to pass through cell membrane
