The correct order of C l – O bond lengths in ClO − , ClO 2 − , ClO 3 − , ClO 4 − is
Options
- AClO − < ClO 2 − < ClO 3 − < ClO 4 −
- BClO 4 − < ClO 3 − < ClO 2 − < ClO −
- CClO 3 − < ClO 4 − < ClO 2 − < ClO −
- DClO 4 − = ClO 3 − < ClO 2 − < ClO −
Correct answer
B. ClO 4 − < ClO 3 − < ClO 2 − < ClO −
Step-by-step solution
Bond length is inversely proportional to bond order. Greater the delocalization of π e - ( - v e c h a r g e ) shorter the bond length.
