If the addition is 5 → hybridization−sp3d. For main group molecules, chemists (like Pauling) thought a long time ago that hypervalence is due to expanded s 2 p 6 octets. hybridisation of IF7. Am. Hybridization of ClF3 - Chlorine Trifluoride is sp3d hybridized. Types of Hybridization (1) sp-hybridization: The combination of one s and one p-orbitals to form two hybrid orbitals of equal energy is known as sp-hybridization. Give balanced equations for the chemical reactions involved. This stress is relieved by the formation of more molecules and the equilibrium will shift to the left. The molecule can undergo a pseudorotational rearrangement called the Bartell mechanism, which is like the Berry mechanismbut for a heptacoordinated system. (i) Temperature is increased – the equilibrium will shift to the backward direction as the increase in temperature will be compensated by absorbing heat. 1 ; View Full Answer it is sp 3 d 3 .
