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.

[tex]\bold { H_3PO_4}[/tex]  is the molecule that can have an expanded octet.

Octet Expansion:

It means that the molecule or atom needs more electron than they require in octet rule.

  • These elements are known as hypervalent elements.
  • These element use d-orbital to expand its octet.
  • For Example-  Sulfur, phosphorus, silicon, and chlorine.

[tex]\bold { H_3PO_4}[/tex] has 32 valence electrons in its outermost shell instead of 8 valance electrons.

Therefore, [tex]\bold { H_3PO_4}[/tex] is the molecule that have expanded octet.
