In this step, we will put the remaining valence electron on the outer atom first for completing their octet. The four outer atoms are evenly arranged in 3D around the central atom as if at the corners of a regular tetrahedron. A:The centre atom in CCl2F2 will be the least electronegative carbon i.e C. Lone pair on the central carbon atom = L.P(C), The core central carbon atoms valence electron = V.E(C), Number of C-H and C-Br bonds = N.A (C-H and C-Br). The three isomers are . Hybridization involves the mixing of two or more atomic orbitals to form orbitals with the same energy, shape, and size. According to this concept, only valence shell electrons participate in bonding, and hence only they are represented while drawing the lewis structure of an atom. X represent the number of bonded atom to central atom. Hyb of CH2Br2) can then be estimated using the formula below. A represent central atom D) 4. 2.
