Question

31. The shape of the IO3- ion is best described
as
(1) see-saw
(2) T-shaped
(3) tetrahedral (4) Trigonal pyramidal​

Answer 1

Solution :

$\underline{ \boxed{ \bold{ \sf{ \red{ \large{I {O _3}^{ - } \: (Iodate \: ion)}}}}}}$

✏ There are 2 double bonds and 1 single bond between iodine and oxygen.

✏ There is presence of 1 lone pair.

✏ Iodine is central atom.

• Hybridisation:

✏ No. of Bond Pairs = 3

✏ No. of Lone Pairs = 1

✏ Total Pairs = 4

✏ Hybridisation = $\sf\red{SP^3}$

• Shape:

✏ The shape of molecule can be seen as Trigonal Pyramidal with corners of base triange be oxygen atoms and iodine at top.
