Q. Shape of is
Solution:
In this molecule, is the central atom with six valence electrons.
Out of which four are involved in bonding with four -atoms and the remaining two behave as a lone pair .
The possible arrangement of these pairs are as:
Shape of sulphur tetrafluoride molecule In structure
(i) the Ip occupy axial position so there are three lp-bp repulsion at
In structure (ii), the Ip occupy an equatorial position and hence there are two repulsions. Hence, arrangement (ii) is more stable.
The shape shown in structure (ii) is a distorted tetrahedron, a folded square or a see-saw.
