The molecular shapes of are
The same with 2,0 and 1 lone pairs of electrons on the central atom, respectively
The same with 1, 1 and 1 lone pair of electrons on the central atoms, respectively
Different with 0,1 and 2 lone pairs of electrons on the central atom, respectively
Different with 1,0 and 2 lone pairs of electrons on the central atom, respectively
The molecular shapes of will be due to the different hybridisation of the central atom.
SF4 , sp3d hybridisation, here 1 lone pair
CF4 , sp3 hybridisation. here 0 lone pair
XeF4 , sp3d3 hybridisation, here 2 lone pair.
So, Different with 1,0 and 2 lone pairs of electrons on the central atom, respectively. This statement is correct.
Hence, the correct answer is Option (4)
