Is diiodomethane polar or nonpolar

WebDiiodomethane (CH 2 I 2) is an iodine containing organic compound. Its decomposition in acetonitrile initiated by 310nm light has been investigated. ... Diiodomethane has been used as a probe liquid for evaluation of the polar and dispersive components of the surface energy of the catecholamine coated fiber surfaces. WebPolar forces are very important because they are the component of surface energy we control when we perform surface treatments. The dipole-dipole attraction is responsible for the strong adhesion between most adhesives, paints, and inks to surfaces. We can increase the polar component of surface energy radically by cleaning, flame treatment ...
