# The incorrect combination among the following is

$\begin{array}{1 1}(a)\;SF_4\rightarrow \text{see saw}\\(b)\;ClF_3\rightarrow \text{pyramid}\\(c)\;NH_4\rightarrow \text{Tetrahedral}\\(d)\;SF_6\rightarrow \text{Octahedral}\end{array}$

$SF_4$ geometry is see-saw
$ClF_3$ geometry is T-shape but not pyramidal shape.
$NH_4^+$ geometry is tetrahedral
$SF_6$ geometry is octahedral
Hence (b) is the correct answer.
