MCQ
In which molecule all bonds are not equal
- A$SiF_4$
- B$BF_4^-$
- C$XeF_4$
- ✓$SF_4$
✓
Answer
Correct option: D.
$SF_4$
d
$S F_4$ has four bonded atoms and one lone pair. The five electron pairs around sulphur adopt trigonal bipyramidal geometry in which one position is occupied by a lone pair. This Ione pair finds a position that minimizes the number of $90^{\circ}$ repulsions it has with bonding electron pairs. It occupies an equatorial position with two $90^{\circ}$ repulsions. The bonded electrons occupy the axial and equatorial positions. The axial $S-F$ bonds are bent slightly away from the lone pair. Hence, all the bonds in $S F_4$ are not equivalent.
