The molecular shape of the C_2Cl_2 molecule is linear. When two or molecules participate in the bond formation, their orbitals overlap due to the sharing of electrons. As a result, the bonding pairs move away from the lone 2 c 2014 Advanced Instructional Systems, Inc. and NC State College of Sciences Foundation. These overlapped orbitals are called hybrid orbitals. We'll look on the periodic table: Carbon has 4 valence electrons, it's in group 4 or 14, but we have two Carbons. They are generally reduced from the values given in Figure 6.1 by interaction with lone pairs. The valence-shell electron-pair repulsion (VSEPR) theory is based on the electron groups around the central atom. So, in addition to 4 sigma bonds, for each additional sigma, added one d orbital gradually as follows:-5σ bonds = 4σ bonds + 1 additional σ bond = sp 3 d hybridization.
