What is the structure and structural characteristic of dichlorine heptaoxide (Cl2O7)?

Avarage oxidation state of Chlorine in Cl2O7 is one of the common oxidation state of the chlorine so there is (Cl-O-Cl) Oxy-linkage will be present. And one of oxygen atom is shared by both of chlorine atoms and rest of the oxygen atoms equally distributed.

The whole molecule dichlorine heptaoxide (Cl2O7) is non planer and polar and oxygen aotm of (Cl-O-Cl) oxy-linkage does not involve in delocalization due to maximum repulsion hence two Cl-O bond have equal length and bond order may be/equal to one while other six Cl=O bond have eqaual bond length.

In dichlorine heptaoxide (Cl2O7) , two ClO4 group connected with an oxygen atom which is sp3 hybridised (non planer) and bond angle may be expected 109⦁28’ but actually due to the presence of two lone pair on oxygen atom the Cl-O-Cl bond angle deviated from ideal and it may be greater (119⦁) than ideal bond angle.

Question (1): Number of sigma  and pi bonds present in Cl2O7 is/ are ....?

Answer: Number of sigma and pi bond present in Cl2O7 are (8) and (6) repectively.

Question(2):What is the anhydride of  HClO4 ?

Answer: Cl2​O7​ is the anhydride of  HClO4

Question (3):Number of equivalent Cl-O bond in Cl2O7 is/are….

Answer Number of equivalent Cl-O bond in Cl2O7 are (2) two.

 

Question(4):Number of equivalent Cl=O bond in Cl2O7 is/are….

Answer:Number of equivalent Cl=O bond in Cl2O7 are (6) six.
