Since two of the atoms … This difference in electronegativity generates a net dipole moment across the bond and makes it a polar. Wear proper footwear to cover the entire foot. CH2Cl2 is used to extract chemicals from plants to make steroids, vitamins, and antibiotics. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. Answer =  ClF  (Chlorine monofluoride)  is  Polar What is polar and non-polar? Mathematically, the dipole moment of a molecule can also be termed as the product of the magnitude of the charge on atoms and the distance between the centers of them. While dichloromethane is relatively polar, it is not as polar as water and teeters on the edge of being a non-polar substance. However, as with many properties, the polarity is a continuous scale, and the correct question is not "is it polar or non-polar" but "how polar is it." Polarity underlies a number of physical properties including surface tension, solubility, and melting and boiling points." Higher electronegative atom attracts the shared bonded electrons slightly towards its side and gains a partial negative charge and other atom gains partial positive charge. The total number of valence electrons in the CH2Cl2 molecule is 20. The shape of the molecule: Another factor that determines the polarity is the shape of a molecule. Dichloromethane is an organic solvent and therefore it can dissolve many non-polar organic molecules (establishing London type interactions). Dichloromethane is a volatile, colourless liquid, with a mildly sweet, not unpleasant odour. Both molecules are tetrahedral, but chloroform is very polar because it has the electronegativity of three chlorine atoms pulling electrons away from the carbon and hydrogen. It has been used as a versatile solvent to dissolve various organic compounds in many chemical processes since World War II. Currently, dichloromethane is manufactured by two sets of processes, hydrochlorination of methanol and direct chlorination of methane. Chlorine being more electronegative than hydrogen causes the dichloromethane molecule to be slightly more negative on the side of the chlorine atoms.
