So, 5σ bonds = 4 σ bonds + 1 additional σ bond = sp 3 d hybridizationī. So, out of 6 electrons, 4 electrons form 4 I-F bonds i.e. IF 4 +: I has 7 e - s in its outermost shell, so, in this case, subtract one e - from 7 i.e. So, in addition to 4 sigma bonds, for each additional sigma, added one d orbital gradually as follows:-ĥσ bonds = 4σ bonds + 1 additional σ bond = sp 3d hybridizationĦσ bonds = 4σ bonds + 2 additional σ bonds = sp 3d 2 hybridizationħσ bonds = 4σ bonds + 3 additional σ bonds = sp 3d 3 hybridizationĪ. In case of sp 3d, sp 3d 2 and sp 3d 3 hybridization state there is a common term sp 3 for which 4 sigma bonds are responsible. Prediction of sp 3d, sp 3d 2, and sp 3d 3 Hybridization States hybridization state of both C’s are sp 2. So, in this case, power of the hybridization state of both C = 3-1 = 2 i.e. In CH 2=CH 2: each carbon is attached with 2 C-H single bonds (2 σ bonds) and one C=C bond (1 σ bond), so, altogether there are 3 sigma bonds. hybridization state of I and Cl both are sp 3.Į. In I-Cl: I and Cl both have 4 σ bonds and 3LPs, so, in this case power of the hybridization state of both I and Cl = 4 - 1 = 3 i.e. hybridization state of O in H 3BO 3 is sp 3.ĭ. On the other hand, power of the hybridization state of O = 4-1= 3 i.e. In H 3BO 3: - B has 3σ bonds (3BPs but no LPs) and oxygen has 4σ bonds (2BPs & 2LPs) so, in this case power of the hybridization state of B = 3-1 = 2 i.e. hybridization state of O in H 2O = sp 3.Ĭ. So, altogether in H 2O there are four σ bonds (2 bond pairs + 2 lone pairs) around central atom O, So, in this case power of the hybridization state of O = 4-1 =3 i.e. two sigma (σ) bonds and two lone pairs i.e. In H 2O: central atom O is surrounded by two O-H single bonds i.e. Therefore, in this case power of the hybridization state of N = 4-1 = 3 i.e. So, in NH 3 there is a total of four σ bonds around central atom N. three sigma (σ) bonds and one lone pair (LP) i.e. In NH 3: central atom N is surrounded by three N-H single bonds i.e. In addition to these each lone pair (LP) and Co-ordinate bond can be treated as one σ bond subsequently.Ī. Power on the Hybridization state of the central atom = (Total no of σ bonds around each central atom -1)Īll single (-) bonds are σ bond, in double bond (=) there is one σ and 1π, in triple bond (≡) there is one σ and 2π.
