Polarity and Structure of CH2Cl2

The video explores whether CH2Cl2, known as dichloromethane, is polar or non-polar. It concludes that CH2Cl2 is a polar molecule due to its asymmetrical structure and the difference in electronegativity between its atoms. The video explains that the chlorine atoms are more electronegative, creating partial negative charges, while the hydrogen atoms have partial positive charges. This results in a polar molecule with distinct positive and negative poles.
