Which of the following species are pyramidal in shape?  

${\mathrm{ClF}}_3\to \mathrm{T}$-shaped The three hydrogen atoms and an unshared pair of electrons connected to the nitrogen atom form the trigonal pyramidal geometry of the ammonia molecule.
The molecule ${\mathrm{XeO}}_3$ will exhibit lone pair-bond pair repulsion as a result of the existence of a lone pair on the central atom, Xenon. In order to create pyramidal geometry, the trigonal planar geometry will be distorted.
