Simultaneously, both hydrogen atoms will achieve their respective duplets, and both chlorine atoms will achieve their respective octets, and thereby the situation will be a win-win for all five atoms. As a result, it has the permanent dipole moment. Your email address will not be published. Required fields are marked *. (7 6 2/2) = 0 formal charge on chlorine atoms. Each C-Cl bond carries two electrons because each carbon atom is connected to two chlorine and two hydrogen atoms by two C-Cl and C-H bonds. Here in the CH2Cl2 molecule, if we compare the carbon atom (C) and chlorine atom (Cl), then the carbon is less electronegative than chlorine. Hydrogen is a period 1 element, so it can not keep more than 2 electrons in its last shell. The carbon-chlorine bonds in dichloromethane(CH2Cl2), for example, are polarised toward the more electronegative chlorine, and because both bonds have the same size and located around four terminals with two chlorine and two hydrogen atoms, their sum is non zero due to the CH2Cl2 molecules bond dipole moment and the lone pairs of electron on two chlorine atoms.
