The CH2Br2 Lewis structure is a diagram that illustrates the number of valence electrons and bond electron pairs in the CH2Br2 molecule. This arrangement results from sp 2 hybridization, the mixing of one s orbital and two p orbitals to produce three identical hybrid orbitals oriented in a trigonal planar geometry (Figure \(\PageIndex{5}\)). So let's go with this right here for now. As a result, wrap around the central carbon atoms bond pair valence electrons first (see figure for step1). The structure of cobr2 does not contain any lone pair of electron on central c atom; hence distortion of ideal trigonal planner structure does not occur. The carbon atom completes its molecular stability in the CH2Br2 molecule because it possesses 8 electrons in its bond pairs with two bromine and two hydrogens in the outermost valence shell. Therefore, formal charge on C+ H1+ H2+ Br1+ Br2 = 0. is then it will be sp hybridization of carbon. In the ground state, C has 2 unpaired electrons. Hydrogen valence electron = 1.
