Identify the molecule in which the arrangement of electron pairs around the central atom is octahedral and shape is not octahedral.

Options

  1. ASF ₆
  2. BXeF ₆
  3. CBrF ₅
  4. DXeO ₂ ~F ₄

Correct answer

C. BrF ₅

Step-by-step solution

The arrangement of electron pairs around the central atom is octahedral and shape is not octahedral can be identified with the help of presence of lone pair (lp) of electrons and bond pair (b p) of electrons associated with the central atom. The structure of given species are : (i) S F ₆ Central atom sulphur has 6 valence electrons, which are bonded with 6F-atoms, thus have octahedral shape. (ii) X e F _ 6 Central atom, Xe have 8 valence electrons, out of which 6 are bonded with 6 ~F -atoms and one l p of electron
