All Of These


Explanation for correct option:

D. All of these

Non-bonding electrons:

  • A non-bonding electron is an electron not involved in chemical bonding.
  • A lone pair can be considered a non-bonding electron pair as it does not participate in chemical bonding.

A. SF4

  • SF4 has a trigonal bipyramidal shape with sp3dand one lone pair of electrons.

B. SO2

  • SO2 has a bent shape with sp2hybridization with one lone pair of electrons.

C. ICl3

  • ICl3 has a trigonal bipyramidal shape with sp3dand two lone pairs of electrons.

Hence, the correct option is D i.e. All of these as all the molecules have non-bonding electrons.
