Explain why `PCl_(5)` is trigonal bipyramidal whereas `IF_(5)` is square pyramidal ?

Among the following statements:- I. PCl_(5) is trigonal bipyramidal wheras IF_(5) is square pyramidal. II. Bond enthalpy of O-H bond in water and ethanol is different. III. All carbon atoms have same hybridisation in carbon suboxide (C_(3)O_(2)) Find out the correct statements.

PCl_5 has a shape of trigonal bipyramid whereas IF_5 has the shape of a square pyramid. It is due to

PCl_3 has the shape of a trigonal pyramid, whereas IF_5 has the shape of a suquare pyramid. Account for this difference.
