Q. Two type FXF angles are present in which of the following molecules? (X=S, Xe, C)
A) $SF_{4}$
B) $XeF_{4}$
C) $SF_{6}$
D) $CF_{4}$
Explanation
(a)
FXF angles of two types are present in $sp^{3}d$ hybrid orbitals. Since, $SF_{4}$ shows $sp^{3}d$ hybridisation as follows, therefore, it exhibits two different FXF angles.
