Which of the following has been arranged in orderr of decreasing bond dissociation energy:

Options

A. `P-O gt Cl-O gt S-O`
B. `P-O gt S-O gt Cl-O`
C. `S-O gt Cl-O gt P-O`
D. `Cl-O gt S-O gt P-O`

Answer

D

Explanation

Bond dissociation enegy `prop(1)/("Bond length")`
Order of bond length: `P-O gt S-O gt Cl-O` order of BDE: `Cl-O gt S gt O gt P-O`
