I thought the answer to which of these shapes is not planar would be ClF3 since I thought it is t-shaped. Why is the correct answer PCl3? PCl3 is trigonal pyramidal, right?

In PCl3 we have 1 lonepair of electrons at phosphorous and 3 Single bonds to each chlorine. It is similar like ammonia shape.

BCl
3 is
trigonal planar which is planar shape.
ClF
3 is
T shaped which is also
planar - all 4 atoms in the same plane.
XeF
4 is
square planar in which all 5 atoms are in the same plane.
However ,PCl
3 is trigonal pyramidal which means it is non planar like a tetrahedral in which P atom is making a pyramid on the base of three chlorine atoms.
