VSEPR theory helps to determine the molecular geometry as well as the bond angle of a molecule. can only fulfil duplet (having two electrons in its valence shell) rather than octet. Here in the CH2Cl2 molecule, if we compare the carbon atom (C) and chlorine atom (Cl), then the carbon is less electronegative than chlorine. Please note that several atoms follow the octet rule, i.e., they tend to achieve eight electrons in their valence shell through chemical bonding; this is reflected in the Lewis structure of the molecule. It is a common solvent in chemistry labs around the world. So, now only six electron pairs are remaining to mark as lone pairs. And when we divide this value by two, we get the value of total electron pairs. "text": " Valence electron in hydrogen atom = 1 Because the central atom is bonded with at least two other atoms, and hydrogen has only one electron in its last shell, so it can not make more than one bond. of CH2Cl2 is shown below. [ 2 dot electrons means one lone pair). Still, the dipole moment of the C-Cl bond will not cancel out because the C-H bonds are almost nonpolar(due to a small electronegativity difference), hence, the weak dipole of C-H bonds is unable to cancel out the strong dipole of C-Cl. and a melting point of -96.7 C. Hydrogen atoms already completed their octet since they are joined with one single bond means 2 electrons and remember, hydrogen only needs 2 electrons to have a full outer shell.
