Question
TBonding A T bond arises from "sideways" overlap of two parallel p orbitals. The electron density lies above and below a plane containing the 2 nuclei that is perpendicular to the orbitals. 8-8-88 p-orbital p-orbital atom1 atom2 T bond The maximum number of? bonds that the atom can form is an atom has sp3d hybridization in a molecule maximum number of p-p T bonds that the atom can form is e maximum number of? bonds that the aton can form is If an atom has sp hybridization in a molecule The maximum number of p-p T bonds that the atom can form isExplanation / Answer
1) 6, 0
2) 2, 2
1) One s, three p and two d orbitals of the atom combine to give six sp3d2 hybrid orbitals. Each of these hybrid orbitals can form one sigma bond, so that a total of six sigma bonds will be formed by the atom. Sideways overlap of unhybridised p orbitals give rise to p-p pi bonding. Since all the three p orbitals are used for sigma bonding, there are no unhybridised p orbitals and no pi bonds will be formed.
2) One s and one p orbitals combine to give two sp hybridised orbitals, each of which can form one sigma bond. Thus a total of two sigma bonds will be formed. The remaining two unhybridised p orbitals overlap sideways to form two pi bonds.
