The correct order of C l - O bond lengths in C l O - , C l O 2 - , C l O 3 - and C l O 4 - is

Options

  1. AC l O - < C l O 2 - < C l O 3 - < C l O 4 -
  2. BC l O 4 - < C l O 3 - < C l O 2 - < C l O -
  3. CC l O 3 - < C l O 4 - > C l O 2 - > C l O -
  4. DC l O 4 - = C l O 3 - = C l O 2 - = C l O -

Correct answer

B. C l O 4 - < C l O 3 - < C l O 2 - < C l O -

Step-by-step solution

The correct order of C l - O bond lengths in C l O - , C l O 2 - , C l O 3 - and C l O 4 - is as follows C l O 4 - < C l O 3 - < C l O 2 - < C l O - Bond length ∝ 1 B o n d order or Bond length ∝ 1 Extent of delocalization
