The molecule of dibromomethane (with tetrahedral shape CH2Br2 molecular geometry) is tilted at 112.5(H-C-H) and 113.4(Br-C-Br) degrees. Due to the difference in electronegativity value of less than 0.5, the C-Br bond of the CH2Br2 molecule becomes less polar. A quick way to learn the concept of the hybridization model is as follows: Step 1: Check the central atom and count the atoms connected with it. The dibromomethane chemical formula is CH2Br2. We're still only using 24 valence electrons, but this Carbon has 8 valence electrons, and now this Carbon here has 8. If there is then it will be sp hybridization of carbon. This indicates that these atoms are chemically bonded with each other in a C2Br2 molecule. The carbon-bromine bonds in dibromothane(CH2Br2), for example, are polarised toward the more electronegative bromine, and because both bonds have the same size and located around four terminals with two bromine and two hydrogen atoms, their sum is non zero due to the CH2Br2 molecules bond dipole moment and the lone pairs of electron on two bromine atoms. In the case of Dibromine, or Br2, both the Bromine atoms have 7 electrons in their outermost valence shell. . We have 24 valence electrons. To form cobr2, 4 unpaired electrons is required.

In the Lewis structure of CH2Br2, the formal charge on the central carbon atom is zero. In cobr2, central c atom uses sp2 hybrid orbital. Then place no electrons as a lone pair of electrons on the carbon atom of the CH2Br2 molecule. The CH2Br2 molecule has a tetrahedral molecular geometry because there is no electrical repulsion between lone pair and bond pairs of CH2Br2 molecule. Finally, you must add their bond polarities to compute the strength of the C-Br bond (dipole moment properties of the CH2Br2 molecule). Before drawing the Lewis structure, we need to know the number of valence shell electrons on all constituent atoms and their sum. So we've filled the outer shells in all the atoms in the C2H2Br2 Lewis structure, and we've used 24 valence electrons. Dipole moment is a vector quantity. Atoms lose or gain electrons to have eight electrons in their valence shell to attain a noble gas-like configuration. The H-C-H and Br-C-Br bond angles generate 112.5 and 113.4 degrees in the tetrahedral molecular geometry respectively. To calculate the valence electron . As cobr2 has planner structure all the atoms in cobr2 lie in the same plane. Being in the same group as Fluorine, Chlorine, and Iodine, it exhibits similar chemical properties.
