One type of exception to the octet rule are compounds with central atoms having fewer than eight electrons around them. So what that means is my oxygen sees this and those lone pairs are nucleophilic so it attacks the phosphorus, OK? It can be used to make trioctylphosphine oxide (TOPO), used as an extraction agent, although TOPO is usually made via the corresponding phosphine. c. The sigma bond between O and P is formed by the overlap of an sp 3 hybrid orbital on P and an sp 2 hybrid orbital on O. d. The 3 B. It has a trigonal pyramidal shape, owing to the lone pairs on the phosphorus. Hence, the P atom is going to be the central atom. POCl3 NF3 ClO2-SO42- SO32- SCl2. The single positive charge reduces that by 1 – giving 8 electrons in 4 pairs. Important Points To Remember.
