Question

Which one of the following are correctly arranged on the basis of the property indicated?

Options

• I₂ < Br₂ < F₂ < Cl₂ [increasing bond dissociation enthalpy]

• H₂O > H₂S < H₂Te < H₂Se [increasing acidic strength]

• NH₃ < N₂O < NH₂OH < N₂O₅ [increasing oxidation state]

• BiH₃ < SbH₃ < AsH₃ < PH₃ < NH₃ [increasing bond angle]

Answer 1

BiH₃ < SbH₃ < AsH₃ < PH₃ < NH₃ [increasing bond angle]
