Assume that central atoms are hybridized.2. Assume that multiply-bonded terminal atoms are hybridized.3. Assume that singly-bonded terminal atoms are not hybridized.Hybridization Tablesum234hybrid setspsp2sp3numberof HOs234arrangementof HOslineartrigonal planartetrahedral+,*Compare:**VSEPR e.g.a.****linear**trigonal planar**tetrahedral*.-Valence Bond Steps1.Start with the Lewis structure.2.Identify which atoms are hybridized and which are not.3.For atoms which are hybridized, determine the hybridization set. Find the sum of the number of bonded atoms and the number of lone pairs, and use this sum to determine
