Question

hypervalent ion is/are

(a) SO3 2-

(b)PO4 3-

(c)SO4 2-

(d)ClO4 -

Answer 1

Hey dear,

● Hypervalent molecule -
- Hypervalent molecule is a molecule that contains one or more main group elements apparently bearing more than eight electrons in their valence shells.

● Explaination -
- Valence electrons in (SO3)2- => 8
- Valence electrons in (PO4)3- => 10
- Valence electrons in (SO4)2- => 12
- Valence electrons in (ClO4)- => 14

Therefore, (PO4)3-, (SO4)2-, (ClO4)- are hypervalent compounds.

Hope this helps you...
