Also, determine the total number of and bonds in the molecule. The octahedral shape is characterized by bond angle values of 90° and 180°. (b) In B e C l 2, hybridisation is s p and hence bond angle is 180 o. In B r F 5 there are 5 bond pairs and 1 lone pair on B r atom. Octahedral: It describes the shape of compounds with six atoms or ligands symmetrically arranged around a central atom. What is the shape of the IF7 molecule likely to be? The IF7 molecule has a pentagonal bipyramidal structure. This is But due to lone pair lone pair repulsions, the bond angle decreases from 109. The molecule for which deviation from a normal bond angle is observed, V S E P R theory suggests electron pair repulsive interaction (l p − l p > l p − b p > b p). So, option C is wrong. The lewis structure of PCl 5 contains a total of 5 bond pairs and 15 lone pairs(3 lone pairs on each chlorine atom). (T) All The only known heptacoordinated interhal- ogen compound is IF7 which has been found to have a distorted pentagonal bipyramidaL structure which undergoes essentially free pseudorotation [5,6].
