Choose the best Lewis structure for SF4.

Choose the best Lewis structure for SF₄.

Expert Solution

Flourine froms single bonds

So answer must be among A and D

Find SF4 hybridisation using fromula

--> [6 + 4] / 2 = 5 = sp3d

Fomula = Central atom valence electrons + No of single bonded atoms / 2

sp3d --> trigonal bipyramidal

but due to one lone pair ; trigonal bypyramidal structure changes to seesaw or k type of structure (because lone pair sits at one of the

axial positions )

From the given options

we can say A is the right answer as it obeys the above criteria

Answer = A
