SATHEE: Chemical Bonding and Molecular Structure

Chemical Bonding and Molecular Structure - Result Question 30

####31. Which of the following would have a permanent dipole moment?

(a) $S i F_{4}$

(b) $S F_{4}$

(d) $B F_{3}$

[2005]

Show Answer

Solution:

(b) $S F_{4}$ has permanent dipole moment. $S F_{4}$ has $s p^{3} d$ hybridization and see saw shape (irregular geometry).

$μ \neq 0$

Whereas $X e F_{4}$ shows square planar geometry, $S i F_{4}$ has tetrahedral shape and $B F_{3}$ has Trigonal planar shape. All these are symmetric molecules. Hence $_{μ} = 0$ .
