Write 5 pages thesis on the topic chemical principles. (a) ClOF4- Cl has 7 electrons in its outer most shell. 5 electrons shared with the atoms around it while there is one lone pair. This means that there are a total of 6 electron domains. Therefore the shape is square pyramidal and the hybridization is sp3d2.

(b) (CH3)2TeCl2 It has 6 electrons in its outer most shell. 4 of them are shared with the molecules around it while 2 are the lone pairs. This indicates that there are a total of 5 electron domains. Therefore Te has an sp3d hybridization having the molecular shape of see-saw. And a bond angle of 90 and 120.

(c)ICl2- The ICL2- molecule has I as Iodine has Iodine as its central atom. The iodine molecule has 7 electrons, two of which have been donated to the Cl molecules satisfying their octet. The iodine has a negative charge, meaning that it also has eight electrons. 3 lone pairs and one shared with each chlorine. The total electron domains are hence 5 indicating that Iodine has an sp3d hybridization. The shape hence becomes linear with the angle approximately equal to 180o.
