The central iodine atom in triiodide has sp3d hybridization.In triiodide anion, the central iodine atom has three equatorial lone pairs of electrons and the terminal iodines are bonded axially in a linear shape. Electrons in sp3d hybridization are arranged in trigonal bipyramidal symmetry.
Step-by-step explanation:
When you draw the Lewis structure of this particle, you'll realize that the central I atom has a pair of bonds and three individual pairs of electrons. as a result of there are five things around that central I atom, it's sp3d hybridized.
The bonds during a gas (CH4) molecule are fashioned by four separate however equivalent orbitals; one 2s and 3 2p orbitals of the carbon interbreed into four sp3 orbitals. within the ammonia molecule (NH3), 2s and 2p orbitals produce four sp3hybrid orbitals, one among that is occupied by a lone try of electrons.
