trigonal bipyramidal orientation This type of bonding occurs in compounds like PCl5 Note that this hybridization is an exception to the octet rule 3 2 sp d hybridization occurs when one s, three p, and two d orbitals are mixed, giving an octahedral arrangement SF6 is an example Again, this hybridization is an exception to the octet rule If one starts with this structure and one of the bonding pai
