A) tetrahedral
B) square planar
C) trigonal pyramid
D) see-saw
Correct Answer: D
Solution :
In this molecule, S is the central atom with six valence electrons. Out of which four are involved in bonding with four F-atoms and the remaining two behave as a lone pair \[(lp).\] The possible arrangement of these pairs are as: Shape of sulphur tetrafluoride\[(S{{F}_{4}})\] molecule In structure (i) the Ip occupy axial position so there are threelp-bp repulsion at\[{{90}^{o}}.\]In structure (ii), the Ip occupy an equatorial position and hence there are two \[lp-bp\]repulsions. Hence, arrangement (ii) is more stable. The shape shown in structure (ii) is a distorted tetrahedron, a folded square or a see-saw.You need to login to perform this action.
