NEET 2022, Chemistry Q24: Valence Shell Electron Pair Repulsion (VSEPR) Theory

NEET2022Chemistry
Q.

Amongst the following which one will have maximum 'lone pair-lone pair' electron repulsions ?

  1. A

    IF

  2. B

    SF

  3. C

    XeF

  4. D

    ClF

Solution

Count the lone pairs on the central atom using VSEPR.

IF (square pyramidal): 1 lone pair on I.

SF (see-saw): 1 lone pair on S.

XeF (linear): 3 lone pairs on Xe, occupying equatorial positions of a trigonal bipyramid.

ClF (T-shaped): 2 lone pairs on Cl.

With three lone pairs, XeF has the largest number of lone pair to lone pair repulsions.
