The molecule that can have an expanded octet is H3PO4.
An expanded octet refers to a situation in which a compound has more than the required number of valence electrons in its outermost shell. The required number of valence electron is 8 but a compound with an expanded octet can have up to 35 electrons in its outermost shell. An example of such a compound is H3PO4, which has 32 valence electrons in its outermost shell.
