Limitations of The Octet Rule -

Many covalent molecules have central atoms that do not have eight electrons in their Lewis structures. These molecules fall into three categories:

  • Odd-electron molecules have an odd number of valence electrons, and therefore have an unpaired electron.

  • Electron-deficient molecules have a central atom that has fewer electrons than needed for a noble gas configuration.

  • Hypervalent molecules have a central atom that has more electrons than needed for a noble gas configuration.

-

As we have learnt,
The octet rule cannot be applied to the non- metals after silicon. These elements can “expand their octet” and have more than eight valence electrons around the central atom.
Hence option number(2) is correct
