2. Hybridisation in [I 3 ] - I (Z=52)  [Kr]4d 10 , 5s 2 , 5p 5 , 5d I in ground state I - in excited state 5s 5p 5d I - in hybrid state I - in ground state sp 3 d I (Z=52)  [Kr]4d 10 , 5s 2 , 5p 5 , 5d pentagonal bipyramid?

3. L.P. L.P. L.P. L.P. L.P. L.P. - - Incorrect Correct (linear) Compare L.P. – L.P. angle B.P. B.P angle Shape of [I 3 ] - = iodine atom What about [ICl 2 ] - ?

4. Hybridisation in [ICl 4 ] - I (Z=52)  [Kr]4d 10 , 5s 2 , 5p 5 , 5d I in ground state I - in excited state 5s 5p 5d I - in hybrid state I - in ground state sp 3 d 2 Cl (Z=19)  [Ne]4d 10 , 3s 2 , 3p 5 , 3d Octahedral?

5. Shape of [[ICl 4 ] - L.P. L.P. L.P. L.P. - - Correct (Square planar) Incorrect (Distorted) = iodine atom = chlorine atom
