Question

Bonding A bond anses rom sideways overlap of two parallel p orbitals. The electron density lies above and below a plane contaming the 2 nuclei that is perpendicular to the orbitals. p-orbital p-orb tom atom t bond The maximum number of bonds that the atom can form is If an atom has sp3d2 hybridization in a molecule: maximum number of p-p bonds that the atom can form is The maximum number of bonds that the atom can form is If an atom has sp3 hybridization in a molecule The maximum number of p-p t bonds that the atom can form is

Explanation / Answer

sp3d2 hybridization is in SF6 and we have 6 sigma bonds(maximum) formed around sulphur atom. Maximum no of pi bonds is zero as fully hybridized orbitals cannot form pi bonds.

sp3 hybridization is observed in CH4, we have 4 sigma bonds(maximum) around carbon atom. Maximum no of pi bonds is zero as fully hybridized orbitals cannot form pi bonds. (However there is an exception in the case of POCl3 which has 1 pi bond)
